Considerations
•
The TSCODE-supported FAULT procedure should only be called from the
USER^REPLIES exit with its noretn parameter equal to 0. See the description of
the FAULT procedure in Section 8.
•
USER^REPLIES is an integer function called only by TSCODE, never by
USCODE. USCODE returns function values to TSCODE with the TAL RETURN
statement. The permissible returned function values are described under the
status variable above.
•
USER^REPLIES is called from the monitor task.
