The CA DADS PLUS for CICS file DADSGRF can hold at least 200 SYSID records. The CA DADS Plus for CICS DADM online transaction can be used to add and update the DADSGRF SYSID records. The DADM screen used to adds the SYSID records has 13 columns and 15 rows.
13 times 15=195. Once you fill in the first screen you will receive a second screen. In my testing I added 200 SYSID records to my DADSGRF file.
