Multi-channel block search
Examples
Two examples for configuring a user-specific SERUPRO end ASUB.
Example 1: Deleting auxiliary functions and generating the auxiliary function output with AUXFUSYNC(...)
CAUTION
Multi-channel block search and AUXFUDEL / AUXFUDELG
If, for a multi-channel block search in the SERUPRO end ASUBs, auxiliary functions with
AUXFUDEL / AUXFUDELG are deleted from the global list of auxiliary functions, before
calling the AUXFUSYNC function, the channels involved must be synchronized. The
synchronization ensures that before calling the AUXFUSYNC, all delete requests are
processed and a consistent list is available.

; CAUTION!
; If, for a multi-channel block search, auxiliary functions with AUXFUDEL/AUXFUDELG
; are deleted from the global list of auxiliary functions, before the loop to
; generate the subprogram FILENAME with AUXFUSYNC, the channels must be synchronized.
The synchronization ensures that all delete requests were processed
; in all channels and a consistent list is available.
