| USED BY | DESCRIPTION |
|---|---|
| JOIN | Used to hold the most recent JOIN command, if any. |
| MULTIFIND | Used to create the compound data set specified in the JOIN command. As each data set is joined with the previous ones, the record numbers are held in this file. In this way the file holds "intermediate" compound data sets until the final data set is joined, which results in the final select file - QSCMPSEL. 244 files, each 4096 records long |
| REPORT | Used for the NOREPEAT option. |
