S30A abend may occur after MANT task terminates with U2700
The S30A is from a FREEMAIN generated by a FREEPOOL macro. This FREEPOOL is executed for a file never opened (because the dynamic allocation failed). The programmer checked for the file being open and bypassed the CLOSE but not the FREEPOOL.
The MANT task should bypass executing the FREEPOOL macro if the Purge and Report files are not open. This is corrected by PTF RO36794.
