Re: [open-cobol-list] Re : CALL SYSTEM OR CALL "SYSTEM"

[Roger While]

No, you misunderstand. they are just flagged by the compiler.
They are allowed when specifying the "-std=" with other than
default, cobol85,cobol2002)

In other words, if you have a prog that passes other then 01
params, then a default compile or a compile with
-std=cobol85 or -std=cobol2002 will produce the
appropiate warning/error - per Cobol standard.

ie: NOTHING is disabled. It is checked if this is allowed.
