ACUFH Configuration Variables

Restriction: This topic applies only when a Database Connectors license has been installed via the Micro Focus License Management System, and applies to Windows platforms only.

Before running , you must set the A_CONFIG environment variable to the name of the ACUFH configuration file. You may want to make and use a personalized copy of the ACUFH configuration file to avoid impacting other users. You could use the A_CONFIG environment variable to identify a personal ACUFH configuration file. For example:

SET A_CONFIG=directory name\file name

defines a configuration file with the name of your choice in the directory of your choice.

There are several variables that can be set in your ACUFH configuration file that affect the processing. Those listed below are applicable to any relational database management system (RDBMS) with which communicates. Some ACUFH configuration variables are database-specific; those variables are discussed in the individual database sections found in the appendices of this guide.

The following ACUFH configuration variables, briefly described here, apply to any RDBMS. For detailed descriptions, look in the Reference > Configuration Variables section of the Help.

Variable	Description
4GL_2000_CUTOFF	Determines which two-digit years are considered to be in the twentieth century and which are considered to be in the twenty-first century
4GL_8_DIGIT_CUTOFF	Determines whether to use 4GL_2000_CUTOFF for dates that don't use a format string and that are eight digits
4GL_COLUMN_CASE	Tells to leave the case of the field names found in the eXtended File Descriptor (XFD) unchanged
4GL_COMMIT_COUNT	Indicates the conditions under which you want to issue an automatic COMMIT-WORK operation
4GL_CONVERT_DATE_ZERO	Allows to locate and return those records written using the date `01/01/01`
4GL_DB_MAP	Enables you to set one map at a time by using FILE-PREFIX as a list of directories, each of which maps to a different database
4GL_EXTRA_DB_COLS_OK (applies to Windows environments only)	Allows the database table to have more columns than the COBOL program's corresponding file descriptor
4GL_FULL_DATA_TEST	Allows you to specify whether an entire field is tested for illegal data or if only the first field is tested
4GL_IGNORED_SUFFIX_LIST	Lists the case-independent suffixes to ignore when opening Microsoft SQL Server tables or DB2 tables
4GL_ILLEGAL_DATA	Determines how COBOL data considered illegal by the database is converted before it is stored in the database
4GL_JULIAN_BASE_DATE	Sets the base date to be used for Julian date calculations
4GL_USEDIR_LEVEL (applies to Windows environments only)	Provides a method of mapping filenames (with directory information) to table names
4GL_WHERE_CONSTRAINT	Allows you to override any value given in the external variable A4GL-WHERE-CONSTRAINT
DEFAULT_HOST	Designates the file system to be used for newly created files that are not individually assigned
`filename`_HOST	Assigns an individual data file to a file system
FILE_TRACE	Allows you to start file tracing without opening the debugger
XFD_DIRECTORY	Tells the run time system the name of the directory that contains the XFD files built by the compiler
XFD_MAP	Tells the run time system to associate certain filenames with a particular XFD
XFD_MAP_RESETS	Determines whether setting XFD_MAP adds to or replaces the existing value
XFD_PREFIX	Defines a specific series of directories to search for XFD files
