MF, MFLEVEL

Enables forward compatibility with Micro Focus COBOL systems by selectively enabling Micro Focus-specific reserved words and changing the behavior of certain features to be compatible with particular versions.

Syntax:

Properties:

Default:	MF"21"
Phase:	Syntax check
$SET:	Initial

Dependencies:

MF"7" sets DBCS"2" immediately.

If integer > 7, sets DBCS"3" and DBSPACE immediately.

Comments:

Behavior of the BLANK LINE phrase in previous versions of this COBOL system can be implemented using the OLDBLANKLINE directive. Behavior of the NEXT SENTENCE phrase in previous versions of this COBOL system can be implemented using the OLDNEXTSENTENCE directive.

If MF"10" or lower is specified, data names are truncated to 30 characters, for compatibility with earlier versions.

MF"11" contains all reserved words that were enabled by the V3.2 and V3.3 MF-OO directive.

MF"12" contains all reserved words in MF"11" together with additional reserved words added at Mainframe Express 3.0, Net Express 4.0 and Server Express 4.0.
