I would need to know your full details -- e.g. version of CICS/TS,
internal/external translator -- of your installation.
FILE and DATASET are synonyms. The big difference with your two
examples is the automatic error handling of the second version, verses
the manual error handling of the first version.
If you specify the RESP keyword you must check it - it is the same as
if you specify the "NOHANDLE" keyword. Without it, CICS will trap many
abend conditions and end your task.
This works very similar to the Cobol "File-Status" keyword.
