Command
list_call_repeat
Function Causes an unconditional jump to a subroutine that starts at the specified absolute address
(in any desired area of RTC6 List Memory) and executes its body several times.
Call list_call_repeat( Pos, Number )
Parameters Pos Absolute jump address [0…(2
23
–1)].
As with list_call: As an unsigned 32-bit value.
Number Number of repetitions.
As an unsigned 32-bit value.
Number = 0 is treated as Number = 1.
Comments • list_call( Pos ) is synonymous with list_call_repeat( Pos, 1 ) .
• list_call_repeat avoids an empty cycle at the repetition, which otherwise inevitably
occurs with list_call … list_call or list_repeat … list_call … list_until
constructions.
• By list_call_repeat, for example, trajectories (see Glossary entry on page 30) from
micro_vector[*] Commands for runup curves and coast down curves can be seamlessly
joined together with shapes from subroutines.
• An empty cycle must be inserted if at list_call_repeat another subroutine call follows
immediately (nested calls). This can be avoided, if there is for example, at least one
micro_vector[*] Command between two subroutine calls.
• The subroutine start Pos can be located in any part of the RTC6 List Memory area. This
applies in particular directly after list_call_repeat. Thus, the complete RTC6 List
Memory can continuously be used for list commands without reserving a special area
for protected subroutines.
• After a list_return the next processed command is the one which follows directly after
list_call_repeat. However, if the subroutine start follows directly after list_call_repeat,
then the next processed command is the one which follows directly after list_return.
