SMS DATACLAS produces output to SYSPRINT and SYSUT2. Output to SYSPRINT is a report that shows the results of execution.
Output to SYSUT2 is the NAME and Parameter Values for any DATACLAS records successfully retrieved. For example, for the following two commands:
SYSUT2 would contain the following record:
DATACLAS NAME(ABC) RECFM(FB) LRECL(80)
You then could, for example edit, the output file to add FUNC(ISRT) and use it to load DATACLAS values to another SMS file.
