Timeout message
When a time-list element (TLE) set by a call to the SIGNALPROCESSTIMEOUT procedure times
out, a system message -26 (process time timeout) is placed on the $RECEIVE queue to be read
by the caller. (This message is identical to the message generated by SIGNALTIMEOUT except
that the message number is different.)
Example
CALL SIGNALPROCESSTIMEOUT( VALUE , MSG, , TIMERTAG );
