Call up a subprogram when the slave position xxx is passed.
ON sign APOS xxx GOSUB name
sign = + = when the slave position xxx is passed in positive direction
– = when the slave position xxx is passed in negative direction
xxx = slave position in UU
name = name of the subprogram
100 xxx

It is possible to call up a subprogram with the instruction ON APOS, if a specific
slave position (UU) has been passed in positive or negative direction. The instruct-
tion can be useful for positioning and synchronization controls, as well as for CAM
controls and CAM boxes. For example, in order to replace the increasing slave
position in the case of open curves after each cycle by a recurring reference point.
NB!:
– An ON APOS interrupt can be deleted with the command ON DELETE .. GOSUB
– The subroutine to be called up must be defined within the SUBMAINPROG and
ENDPROG identified program.
– During the execution of subprograms triggered by an interrupt, NOWAIT ON is
set automatically.
