Print output data sets

ISPF writes the print output from a debug session to a sequential data set, if you:

Allocate the data set, using the Data Set utility (option 3.2), before you run COBOL interactive debug
Enter, in the Print ID field on the COBOL Interactive Debug panel, the name of the data set you allocated.

You can avoid generating the print output by leaving the Print ID field blank, even if you allocated the data set.

The last qualifier in the name of the data set you allocate must be TESTLIST. For example, if you allocate a sequential data set named DEBUG1.TESTLIST and then specify the Print ID as:

Print ID . . DEBUG1

ISPF writes the print output to a sequential data set named:

'prefix.userid.DEBUG1.TESTLIST'

where prefix is your TSO data set prefix, if you have one and if it is different from your user ID, and userid is your TSO user ID. Use these values to allocate print output data sets:

Record format . . . . . FBA
Record length . . . . . 121
Block size  . . . . . . 3146

The value you put in the Block Size field should be a multiple of 121, the record length. Therefore, if your print output data is too large to fit within the recommended block size (3146), increase this amount by using a multiple of 121, such as 3267 or 3388.
