Summary
Function: list ListStridedRemove( list src, integer start, integer end, integer stride );
Removes each stride from a list, example a list of 1,2,3,A,1,2,3,A after ListStridedRemove(list,4,0,4); would be 1,2,3,1,2,3
Returns a list
| • list | src | |||
| • integer | start | |||
| • integer | end | |||
| • integer | stride |
