; 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)

Comment
; M2=3 (5th auxiliary function group) delete
; Delete the collected auxiliary function of the
; 6. group.
; File already exists and must be
; deleted.
; Procedure to generate
; auxiliary function blocks from the global
; auxiliary function list.
; All auxiliary functions of the channel
; are processed.
; If auxiliary functions are output,
; the block is generated.
