for

The for loop allows iteration a fixed number of times. Note that scripts will only execute a maximum of 5,000 commands before generating a runtime error. This is to keep any script from running out of control.

You can use the 'begin' keyword in place of the statement to execute multiple commands on each iteration. Be sure to terminate the loop with an 'end' statement:

	for X = 1 to 5 begin
		....
	end

usage: for [target] = [expr1] to [expr2] [step [expr3]] [statement] [;] [statement...]

parameters:

req name type description
Y target variable Variable to receive the value of each iteration
Y expr1 expression The starting index of the loop
Y expr2 expression The ending index of the loop
N expr3 expression The increment to use each iteration (defaults to 1, can be negative)
Y statement statement The command(s) to execute on each iteration of the loop

examples

for X = 1 to 5 http get "/execute.php?cmd=" + $X

Interate from 1 to 5, assigning the value of each iteration to X. On each iteration, execute an http statement giving the value of X to the server script being executed.

for X = 5 to 1 step -1 http get "/execute.php?cmd=" + $X

Interate from 5 to 1, assigning the value of each iteration to X. On each iteration, execute an http statement giving the value of X to the server script being executed.
