Generic resources preferences table

Use the generic resources preferences table (GRPREFS) to define how a generic resource resolution is performed. You can define an entry in the table for each generic name; you can also define a default entry. VTAM® does not provide a default generic resources preferences table; however, all generic resource preferences have a default value.

Only one GRPREFS table can be active at a time. The most recently activated GRPREFS table entirely replaces any previously active GRPREFS table.

There is no function to delete a GRPREFS table, however to effectively delete any previous GRPREFS table and return to using the VTAM default generic resource preferences you can activate a GRPREFS table containing only one GRPREF definition statement without a name and without any operands.

Figure 1 shows the definition of a GRPREFS table.
