Short List
Command
sub_call_abs
Function Causes an unconditional jump to an indexed subroutine. In the called subroutine, any
absolute Vector Commands and “Arc” Commands receive an offset (corresponding to the
current coordinates at the time of the call).
Call sub_call_abs( Index )
Parameters Index Index of the called indexed subroutine.
As an unsigned 32-bit value.
Allowed value range: [0…1023].
Comments • sub_call_abs reads the indexed subroutine’s starting address from the internal
management table based on the supplied index and then calls list_call_abs (see also
the comments there). list_call_abs then triggers the jump to the subroutine.
• If the called subroutine contains no absolute commands, then there is no difference
between sub_call_abs and sub_call.

Short List
Command
sub_call_abs_cond
Function Conditional call (AbsCall) of an indexed subroutine: sub_call_abs_cond executes
sub_call_abs( Index ), if the current IOvalue at the 16-bit digital input port of the
EXTENSION 1 socket connector meets the following condition:
((IOvalue AND Mask1) = Mask1) AND (((not IOvalue) AND Mask0) = Mask0)
(= if the bits specified in Mask1 are 1 and the bits specified in Mask0 are 0 ). Otherwise, the
directly following list command is immediately executed.
Call sub_call_abs_cond( Mask1, Mask0, Index )
Parameters Mask1 16-bit mask.
As an unsigned 32-bit value.
Only the lower 16 bits are evaluated.
Mask0 See Mask1 .
Index Index of the called indexed subroutine.
As an unsigned 32-bit value.
Allowed value range: [0…1023].
Comments • See sub_call_abs.
