Command
list_call_abs
Function Causes an unconditional jump to a subroutine that starts at the specified absolute address
(in any desired area of RTC6 List Memory). In the called subroutine, any absolute
Vector Commands and “Arc” Commands receive an offset (based on the current
coordinates at the time of the call).
Call list_call_abs( Pos )
Parameters Pos Absolute jump address [0…(2
23
–1)].
As an unsigned 32-bit value.
Comments • list_call_abs is basically identical to list_call (see comments there). However,
list_call_abs results in a different execution of absolute Vector Commands and
“Arc” Commands within the called subroutine. When list_call_abs executes, an offset
is established for the called subroutine and set according to the current position.
Thereby, the current position is automatically considered when absolute
Vector Commands and “Arc” Commandes of the called subroutine are subsequently
executed. Nested calls are taken into account when the offset is determined (with
list_return, the previous offset values are re-established). Subroutines can thus contain
absolute Vector Commands and “Arc” Commands even if they are intended to be
repeated in different parts of the Image Field.
• If the called subroutine contains no absolute commands, then there is no difference
between list_call_abs and list_call.
• list_call_abs( Pos ) is synonymous with list_call_abs_repeat( Pos, 1 ) .
