GB64 entry for GETB64 macro

Entry:
GB64
VIT option:
SMS
Event:
GetB64 macro
VIT processing module:
ISTRACOT
Control is returned to:
ISTO64GB

This trace record shows the status of each GetB64 request that VTAM® components issue. The FreeB64 macro is the complement of the GetB64 macro. FreeB64 releases the storage that GetB64 obtains. Each GB64 entry should eventually have a corresponding FB64 entry. If the return code is not zero, this entry is generated whether the SMS option is in effect or not. This event is treated as an exception condition and, therefore, is traced whenever the VIT is active.
