{{change|1.3b54|Changed the third parameter from the end value to a count value. In other words, in b53 and earlier, on each iteration it compared if var <= end to determine whether to continue executing the body. In b54+, it is now comparing if var < end, so the body will never see a value of var equal to end.}} | |||

FOR Option
Introduced: Version 1.3.b46
Executes a statement for a number of iterations based on a start and end value.
Usage
[FOR(var, start, end): body]
[FOR(var, start, end, stepsize): body]
[FOR(var, start, end, stepsize, separator): body]The var variable counts from start towards end during the loop, and the optional stepsize (default +1) is added to var at each iteration. Note that in the standard incrementing usage with a stepsize of 1, the body does not execute when var reaches end.
Example
[FOR(i,0,10): "i is now " + i]Counts up from 0 to 9.
[FOR(i,10,0,-2): "i is now " + i]Counts down even numbers from 10 to 0.
