; 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.
; Example: WAITM(99,1,2,3)
