A distinction is made between the following two cases for block
search:
1. The main program MAIN1.MPF is in the NC, the subroutines
SUBPRG1.SPF to SUBPRG3.SPF are processed externally.
2. The main program MAIN1.MPF and the subroutines
SUBPRG1.SPF to SUBPRG3.SPF are processed externally.
Case 1
· Search target 1: The NC does not consider the EXTCALL calls in
lines 3, 5, and 6 of the main program MAIN1.MPF and jumps to
the search target Line 8.
· Search target 2: The NC jumps to the search target at line 4000 of
external subroutine SUBPRG2.SPF; the previous statements in
the external program are skipped.
· Search target 3: The NC jumps to the search target at line 2300 of
external subroutine SUBPRG3.SPF; the previous statements are
skipped, and the search stops.
On NC Start, the subroutine SUBPRG3.SPF is processed starting at
the destination line.
