8.13 Block-search response

Multi-channel block search

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.

Two examples for configuring a user-specific SERUPRO end ASUB.

Example 1: Deleting auxiliary functions and generating the auxiliary function output with AUXFUSYNC(...)

Program code

N10 DEF STRING[400] ASSEMBLED=""

N20 DEF STRING[31] FILENAME="/_N_CST_DIR/_N_AUXFU_SPF"

N30 DEF INT GROUPINDEX[10]

N40 DEF INT NUM

N60 DEF INT ERROR

N140 AUXFUDEL("M",2,3,5)

N170 AUXFUDELG(6)

N190 IF ISFILE(FILENAME)

DELETE(ERROR,FILENAME)

IF (ERROR<>0)

SETAL(61000+ERROR)
