A COBOL batch program doing Datacom calls fails with S0C2 or S0C4 abends after upgrading to z/OS Enterprise COBOL for z/OS version 5.
z/OS Enterprise COBOL for z/OS version 5 requires that the program load module be linked using AMODE=31.
Re-link the COBOL program with AMODE(31) and RMODE(ANY)
In addition, since the program load module has to be AMODE=31, the Datacom URT also needs to have AMODE=31.
To do this, in the URT source, code the following in the DBUREND macro then re-assemble and link the URT:
See section End Macro (DBUREND) in https://docops.ca.com
See TEC1154547 for details on the use of the DBURINF option LE=YES.
