MAPNAME

Makes the Compiler alter program-names and entry-point names to make them compatible with OS/VS COBOL, DOS/VS COBOL, VS COBOL II and COBOL/370.

Syntax:

 >>-.---.-.----.--MAPNAME-------------------><  
    +-/-+ +-NO-+

Parameters:

None

Properties:

Default:	NOMAPNAME
Phase:	Syntax check
$SET:	Initial

Comments:

Specifying MAPNAME affects program-names and entry-point names defined in the compilation and those referenced by the program as follows:

ENTRY statements only in the outermost program
CALL literal, but not CALL identifier, statements
PROGRAM-ID entries in the outermost program, but not in nested programs

When a name is found to be incompatible a warning message is given and a modified name is used in the object program. The rules enforced and the modifications made are:

The first eight characters must be unique among program-names. The name is truncated to the first eight characters.
The first character must be alphabetic. If it is numeric it is changed as follows:
```
0       becomes    J 
1 - 9   become     A - I
```
Hyphen (-) is not allowed. If one appears it is changed to zero (0).
