What maintenance is needed in order for CA Easytrieve release 11.6 to be compatible with COBOL version 5.2?
Easytrieve Report Generator, release 11.6
The following maintenance is for COBOL version 5.x, but please note that none of these are specifically for COBOL 5.2:
RO86966, RO84600, RO82431, RO73486, RO71889, RO66665
If upgrading from COBOL 5.1 to COBOL 5.2, then most likely the above PTFs are already applied for Easytrieve release 11.6.
