Problem conclusion

Temporary fix

Comments

  • The new FLAGMIG4 compiler option for Enterprise COBOL V4.2
    issues warning messages for any compiler option or language
    element that is not supported in Enterprise COBOL V5.1.  Warning
    messages are also issued for language elements that behave
    differently in Enterprise COBOL V5.1 than in Enterprise COBOL
    V4.2.

      Preface, Summary of changes
      Version 4 release 2 add:
    
    | A new compiler option, FLAGMIG4, which enables users to
    | identify Enterprise COBOL V4.2 language elements that are
    | either not supported by or that behave differently in
    | Enterprise COBOL V5.1. FLAGMIG4 also identifies Enterprise
    | COBOL V4.2 compiler options that are not supported or are not
    | accepted by Enterprise COBOL V5.1.

    | FLAGMIG4 identifies Enterprise COBOL V4.2 language elements
    | that are not supported by or behave differently in Enterprise
    | COBOL V5.1.  FLAGMIG4 also identifies compiler options that
    | are not supported or not accepted by Enterprise COBOL V5.1.
    |
    | FLAGMIG4 flags the following language elements that are not
    | supported by Enterprise COBOL V5.1:
    |
    |   - DATE FORMAT clause
    |   - GO TO MORE-LABELS statement
    |   - USE AFTER LABEL declarative
    |   - Intrinsic functions:  DATEVAL, UNDATE, YEARWINDOW
    |
    | FLAGMIG4 flags the following language elements that have
    | behavior changes from Enterprise COBOL V4.2.  In Enterprise
    | COBOL V5.1:
    |
    |   - The linkage convention for returning double-word binary
    |     items is changed to be compatible with the linkage
    |     convention used for such items by C and C++
    |
    |   - A successful read of a file might return file status 04
    |     instead of 00, if the minimum and maximum record sizes
    |     do not match the bounds specified in the RECORD VARYING
    |     clause
    |
    | FLAGMIG4 flags the following compiler options and suboptions
    |
    |   - Options that are not supported by Enterprise COBOL V5.1:
    |        o DATEPROC
    |        o NOLIB
    |        o SIZE(MAX)
    |        o TEST(HOOK, NOHOOK, SEPARATE, NOSEPARATE)
    |        o XMLPARSE
    |        o YEARWINDOW
    |
    |   - Options that are not accepted by Enterprise COBOL V5.1:
    |        o EVENTS
    |        o FDUMP
    |        o FLAGSAA
    |        o PFDSGN
    |        o RESIDENT
    |        o TEST(ALL, BLOCK, PATH, STMT, NONE, SYM, NOSYM)
    |
