Compiler Options

The list below describes each of the Compiler options and its default setting, when applicable.

-#

Provides information on how the Compiler and linker would be invoked without actually invoking them. This option also shows which UNIX options are translated to Micro Focus options; for example, when the standard UNIX -O option is given on the driver command line, it is translated on the Compiler invocation line as -opt.

--agginit

Performs initialzation of aggregates (arrays and structures) compatible with 7.x versions of Open PL/I.

Example:

dcl myarr(4) fixed bin(31) static init (1);
put skip list (myarr);

results in:
             1               1               1               1

By default, without -agginit, only the first element is initialized.

-bigendian

Specifies that all fixed binary items are implicitly declared with the BIGENDIAN data attribute, unless the NATIVE attribute is explicitly applied to a data item.

-c

Suppresses linking and produces a relocatable object file. This option applies to mfplx only.

-check

This option, which can be used only with mfplx, causes the Open PL/I Source Checker to be run instead of the Open PL/I Compiler.

-currency_symbol

Allows an alternate currency symbol for picture specification. It can take a character, decimal number, or hex constant of the form 0xDD, for example, -currency_symbol £, -currency_symbol 163, -currency_symbol 0xa3.

-db2

Invokes the DB2 precompiler, mfdb2. The default DB2 precompiler output file name is xxx.pp2, where xxx is the name of the source file. If the -ppdb2 option is not specified, the file xxx.pp2 is deleted after the compilation phase is completed. The -db2 option applies to mfplx only.

-default_binary

Causes the BINARY attribute to be assumed if the FIXED attribute is specified without BINARY or DECIMAL.

-default_decimal 

Causes the DECIMAL attribute to be assumed if the FIXED attribute is specified without BINARY or DECIMAL. This option is the Compiler default.

-defext

Causes external variables to be defined in the .data section. You must use this option for programs using external files.

The -defext option causes the initialized values of STATIC EXTERNAL variables and external file constants to be defined. Each STATIC EXTERNAL variable that has an INITIAL value must be declared in one and only one module that has been compiled with -defext. Failure to do so causes the INITIAL value to have no effect. The default is -nodefext.

Also, each file constant must be declared in one and only one module that has been compiled with -defext. When -defext is used, file attributes specified in the file declaration will be merged with attributes specified when the file is opened. This is critical when doing VSAM/INDEXED I/O.

-E

Causes any specified precompilers or preprocessor (-macro, -unikix, -db2) to be run on the source file, and saves their output, but stops without running the Compiler.

-exp

Produces an expanded listing of the generated code in the form of assembly language statements in the listing file.

-fdasfb

Causes Float Decimal data to be internally coded as Float Binary. This option produces much faster code but loses precision in the least significant digits of arithmetic results. -fdasfb is the default. See also the -nofdasfb option.

-flag

Specifies the minimum diagnostic level of messages listed in the compiler listing.

-flag minimum diagnostic level

The minimum diagnostic level can be:

I

Emits diagnostic messages beginning at the Informational level (Lists all messages. This is the default).

W

Emits diagnostic messages beginning at the Warning level.

E

Emits diagnostic messages beginning at the Error level.

S

Emits diagnostic messages beginning at the Severe level.

A

Abort.

-fmaxp

Causes extended floating-point precision to be used for the trigonometric built-ins and for the following arithmetic built-ins: EXP, LOG, LOG10, LOG2, SQRT. -fmaxp is the default.

-highbif

This compile-time switch allows changing the value returned by the HIGH() built-in function. For example, -highbif 127 (the default value is 255; the value 127 maybe used for compatibility with earlier versions of Open PL/I).

-ipath dirlist

Directs the Compiler to search specified directories for files to be included in the source program text by use of the %INCLUDE statement. dirlist is an ordered list of directories of the form

dirname[:dirname] ...

-ipath instructs the Compiler to use these directories in the specified order in its search for files to satisfy %INCLUDE statements (except in cases where an absolute directory path is specified in the %INCLUDE statement).

For example, suppose the source program contains:

%INCLUDE partlist;

and the Compiler invocation command is:

mfplx source_file -ipath .:/u/libr1:/u/libr2

In this case, the Compiler will first search for "PARTLIST" in the current working directory, then /u/ libr1, and finally /u/ libr2. If that fails, it will search for "partlist" (lowercase) in the same directories.

In a Windows environment, the equivalent Compiler invocation is:

mfplx source_file -ipath .;drive:\libr1;drive:\libr2

-isuffix string

Causes string to be appended to the filename specified in %INCLUDE statements, except those in which the quoted filename form of the %INCLUDE statement is used.

For example, suppose the source program contains:

%INCLUDE partlist;

and the Compiler invocation command is:

mfplx source_file -isuffix .INC

In this case, the Compiler will search for a file named "PARTLIST.INC".

-l [ file]

Produces a Compiler listing where file is the name of the file to which the listing is output. If you do not supply a filename, you must place this option after the source filename on the command line; otherwise, an error message appears. The default name of the file containing the listing is xxx.list, where xxx is the source filename (excluding the pathname) up to, but not including, the last "." (if any) in the name. For example, if the source filename is prog.pl1, the default listing is prog.list (prog.lst for Windows systems). A Compiler listing is produced by default whenever -exp, -map, or -xref is specified.

-longint

Changes the default precision of Fixed Binary variables from (15) to (31).

-lowercase

Converts all uppercase names of internal and external variables and constants to lowercase.

-macro

Invokes the Open PL/I Macro Preprocessor, mfpp. The default preprocessor output file name is xxx.pp, where xxx is the name of the source file. If the -pp option is not specified, the xxx.pp file is deleted after the compilation phase is completed. The -macro option applies to mfplx only.

-map

Produces a storage allocation map at the end of the listing file.

-margins 1,r

Sets the margins within which characters of the source file are interpreted as source code and outside which all characters are ignored by the Compiler. 1 is the column number of the leftmost character, and r is the column number of the rightmost character to be interpreted as source code. Note that if tabs are used, each tab is counted as a single character. The -margins option can be overridden by a *PROCESS statement in the source.

Note: There must be no spaces around the comma separating the left and right margin.

-names

Adds extralingual characters to identifiers via the compiler options, similar in nature to *PROCESS NAMES().

Example:

-names 'string1' [ 'string2' ]

string1

Extralingual characters to add to identifier.

string2

Corresponding upper case characters. Optional.

The default is:

-names '$@#' '$@#'

When there are no extralingual characters, the compiler option is:

-nonames

-nonames and -names can't be used together as they are conflicting options and cause an error.

-nonames -names ...

For additional characters you must specify the default $@# or subset if desired, plus the additional lingual characters.

-names '$@#Ј'

For convenience, hex constants of the form 0xDD..DD are accepted in place of the strings above.

-names 0x402324a3

-nest

Indicates the nesting level on the listing of DO ... END, PROC ... END, and so on.

-nofdasfb

Causes Float Decimal data to be internally coded as Binary Coded Decimal. The default setting is -fdasfb.

-nofmaxp

Causes standard PL/I conversion rules to be used to determine the precision of trigonometric and certain arithmetic built-ins. The default is -fmaxp.

-noincludes

Directs the Compiler not to include the contents of %INCLUDE files in the listing file. The default is to include file contents in the listing file.

-nomacro

Suppresses the invocation of the Open PL/I Macro Preprocessor. The default is -nomacro.

-[no]namesstring1 [string2]

Provides extended character support. For example,

-names 'string1' ['string2']

where string1 are extralingual characters to add to identifiers, and string2 are optional corresponding uppercase characters. Hex constants of the form 0xDD are accepted in place of the strings. The default is -names.

-noobj

Compiles for syntax and semantic checking only. Does not produce an object file.

-noopt

Compiles without optimization. This is the default.

-norange

Suppresses generation of code to check the validity of subscript references and substring bounds. This option should be used after your program has been debugged to improve execution time performance. The default is -norange.

-not_symbol

Allows an additional NOT symbol. It can take a character, decimal number, or hex constant of the form 0xDD. See also %PROCESS in the Language Reference Manual.

-nounixdebug

Avoids generating the additional object file data needed to report source file and line number when a fatal run-time error occurs, or for use by the ONLOC built-in function.

-nounrefexternals

Prevents external entry symbols that are not referenced in the program from being generated in the object file. This is the default.

-nowarn

Suppresses all WARNING level diagnostics.

-O

Invokes the optimization phase of the Compiler. This option applies to mfplx only and is equivalent to the -opt option.

-o file

Names the object file the name you specify with file. If -o is not specified, the default name of the file is xxx.o, where xxx is the source filename up to, but not including, the last "." (if any) in the name. For example, if the source filename is prog.pl1, the default object filename is prog.o (prog.obj for Windows).

If -c is specified, the -o option is passed to the compiler; if -c is not specified, -o is passed to ldpli.

-oldalign

Causes the Compiler to allocate Character Varying items and align structure members compatible with releases prior to Open PL/I 6.0.

-opt [level]

Specifies the level of optimization by the Open PL/I Compiler, where level stands for the level (1 – 3) of optimization. The default setting is -noopt. If level is not included, the program is optimized at level 3. If -deb is specified, -opt 2 is the maximum level allowed. Note, -opt -deb is equivalent to -opt 2 -deb.

-or_symbol

Allows an additional OR symbol. It can take a character, decimal number, or hex constant of the form 0xDD. See also %PROCESS in the Language Reference Manual.

-pass

Connects to a remote DB2 database. You can use this option with a specified username and password. The format is:

–pass myid.mypass

Where myid is the username and mypass is the password for the remote DB2 connection. mfplx first checks the -pass for a username/password and uses these values if specified. If not specified, it uses the values set for the DB2_USERNAME and DB2_PASSSWORD environment variables.

-pic

Generates position-independent code, suitable for linking into a shared library. This option is only available on Solaris, SUSE Linux and Red Hat Linux.

-pl1g

Causes Open PL/I to retain the behavior of releases prior to Open PL/I 5.0 for certain operations that have been changed in such a way as to become incompatible with that former behavior. For example, TIME() returns a value including three fractional digits (thousandths), but -pl1g causes it to return only two fractional digits (hundredths).

-pp [file]

Specifies the file name for the output file of the Open PL/I Macro Preprocessor. An output file created with the -pp option is preserved after the compilation phase is completed. This option applies to mfplx and mfpp only.

-ppcics [file]

Specifies the file name for the output of the CICS precompiler. An output file created with the -ppcics option is preserved after the compilation phase is completed. This option applies to mfplx only.

-ppdb2 [file]

Specifies the file name for the output of the DB2 precompiler. An output file created with the -ppdb2 option is preserved after the compilation phase is completed. This option applies to mfplx only.

-proto

Provides more extensive prototype checking on arguments vs. parameters in entry declarations (also assumed by default when using -vax).

Example:

declare myproc external entry(
      fixed binary(31),
      fixed binary(15),
      fixed binary(15));

   myproc: procedure(a,b,c);        /* mismatch diagnosed, -proto and -vax */
      declare a fixed binary(15);
      declare b fixed binary(15);
      declare c fixed binary(15);

   end t660;

-range

Validates all static array bound references at compilation time, and generates code to check the run time validity of all subscript references, and substring bounds. Note that the checking code slows down execution time performance.

If array or string bounds are exceeded at run time, the SUBSCRIPTRANGE or STRINGRANGE conditions will be raised, as appropriate. We recommend that this option be used to debug programming errors relating to subscripting and substringing, and that the -norange option be used for debugged code. The default is -norange.

-report [file]

Specifies the file name for the output of the Open PL/I Source Checker. If this option is not used, the output of the checker will be directed to the standard error file. This option applies to mfplx only.

-setnull n

Designates a null pointer value n to be returned by the NULL built-in function, where n is a decimal value. If this option is not specified, the value of the NULL built-in function is an address with all bits set to 1.

-stardesc

Tells the Compiler to produce argument descriptors for calls only when array bounds or string lengths in the parameter declaration are represented by the asterisk (*) symbol. (This was compiler behavior in releases prior to release 7.0.) When this option is not used, the Compiler produces descriptors for array, structure, and string arguments, which can be a problem for very large structures.

-stat

Prints Compiler statistics to the standard output as each Compiler phase completes.

-unaligned

This compile-time switch has been added for use on RISC architectures. This switch causes byte instructions to be generated for all based references, which might point anywhere in memory.

-unikix

Invokes the CICS precompiler, kixplt. The default CICS precompiler output file name is xxx.pp1, where xxx is the name of the source file. If the -ppcics option is not specified, the file xxx.pp1 is deleted after the compilation phase is completed. The -unikix option applies to mfplx only.

-unrefexternals

Causes external entry symbols to be generated in the object file, even if they are not referenced in the program.

-v

Prints information to stdout relating to the compilation and link-step phases. This option applies to mfplx only.

-variant string

Passes the variant string string to the Open PL/I Macro Preprocessor. This option applies to mfplx only.

-vax

Makes the following adaptations for programs originally written with Digital Equipment Corporations's PL/I Compiler for the VAX platform:

• Enables the Fixed Binary(p ≤ 7) data type as a one-byte signed binary integer.
• Enables Float Binary(24) as equivalent to Float Binary(23).
• Enables Float Binary(53) as equivalent to Float Binary(52).
• Causes the BINARY attribute to be assumed if the FIXED attribute is specified without BINARY or DECIMAL.

-warn

Does not suppress level 1 (WARNING) messages. This is the default.

-xref

Produces cross-reference information in the listing file.

-zp1

Causes all structures to be mapped as if the UNALIGNED attribute is specified at the level 1 structure level. This option is for compatibility with versions of DEC VAX PL/I.
