AMODE and RMODE considerations

Static calls between AMODE 24 and AMODE 31 programs are not supported by Enterprise COBOL 5.1.0 programs. Static calls between AMODE 24 programs and Enterprise COBOL 4.2 and earlier programs are supported for the cases where AMODE 24 is supported for Enterprise COBOL 4.2 and earlier programs.

In addition, NORENT programs can no longer reside beyond the line. The following diagram shows the types of calls that can be dynamic or static and those that can only be dynamic. It also shows configurations of data and program location with respect to the 16 MB line.

Note: For other AMODE 24 programs, no calls are allowed between Enterprise COBOL 5 or 6 programs and either OS/VS COBOL or VS COBOL II NORES programs.
