    Dear All,

    .
    Our COBOL env was Enterprise COBOL v4.2. and wish migrate to COBOL v5.2 above.

    Fist, convert for compiler output from PDS to PDSE dataset.
    .
    When we migrate to COBOL v5.2 above,  Is it compatible for COBOL v4.2 modules when upgrade to COBOL v5.2 or v6.1?
    .
    To re-Compile or Not to re-Compile all COBOL v4.2 modules during in migration? thanks.
    .
    Any advice is welcome, Thanks
    .

    See here,https://www.ibm.com/developerworks/community/forums/html/topic?id=6d98d469-5088-41ec-8926-34e945443891&ps=25, for some general advice.

    You do not have to recompile V4.2 programs (or most others, as you can see in the Migration Guide), but there are advantages, to be weighed against not doing so.
