Description
NFILES sets the number of FILESAVE areas.
To open a file for a user, Model 204 must assign a file save area. NFILES is thus the maximum number of files that can be opened by all users at any time. NFILES can range from 1 to 16383 (one less in a run using permanent groups).
This parameter is automatically incremented by a value of one for both CCAGRP and CCASYS.
If the RESTART command is issued by User 0, NFILES must be set to the maximum number of files updated in the previous run.
For Parallel Query Option/204 users, the NRMTFILE parameter allocates file save areas for remote files. NRMTILE and NFILES are, therefore, similar but independent.
