Command for revoking suppression of the display of the current block
Location: At the end of the program line with the PROC operation
Effective: Up to the return jump from the subprogram or end of program.
Note:
If further subprograms are called from the subprogram using the DISPLON com‐
mand, then the current block will also be displayed in these subprograms
unless DISPLOF is explicitly programmed in them.
DISPLOF together with the ACTBLOCNO attribute means that in the case of an
alarm, the number of the actual block is output in which the alarm occurred. This
also applies if only DISPLOF is programmed in a lower program level.
On the other hand, for DISPLOF without ACTBLOCNO, the block number of the cycle
or subprogram call from the last program level not designated with DISPLOF is
displayed.

Comment
; Suppress current block display Instead,
the cycle call should be displayed, e.g.:
CYCLE(X,100.0)
;Cycle contents
; Subprogram return jump. The block follow-
ing the cycle call is displayed in the block
display.
