The TPF system provides exit points for all of the control program user exits listed in this chapter. To create your own control program exit point and user exit, do the following:
Entries in each array correspond to entries with the same subscript in the other 2 arrays. For example, the entries for the nondynamic RIAT exit point are:
&UEP(37) SETC 'RIT' &ATT(37) SETC '00' &DESC(37) SETC 'RIAT EXIT POINT'
The entries for the dynamic overlay fast link macro exit point are:
&UEP(13) SETC 'FLX' &ATT(13) SETC 'UCLDYN+UCLOVR' &DESC(13) SETC 'FAST LINK MACRO EXIT'
Entries can be added by overlaying spare or unused entries or by adding to the end of the arrays. Twelve spare entries have been provided for you.
When adding entries to these arrays it is important to insert new entries at the end of the array, but before the last entry. The last entry in each array marks the end, and must have the following values:
&UEP(n) SETC 'XXX' &ATT(n) SETC '00' &DESC(n) SETC 'END OF TABLE'
where n is the size of the array, increased by the number of exits you have added.
Additions to this array are made in exactly the same way as for the DCTUCL arrays: the subscript is the same for the corresponding entry, and any additions must be made at the end, before the entry that marks the end of the array:
&UEP(n) SETC 'XXX'
