Synopsis

for {variable} {start} {end} { }

Description

The for command controls a loop that iterates a variable over a range of numbers. Both positive and negative iterations are legal.

The variable is assigned the starting number to begin with. After each iteration it either increments or decrements the variable, until it reaches the ending number.


Note: In EasyUO 1.4, you must use brackets, even if there is only a single line of code in a for loop. In EasyUO 1.5 however, brackets are optional when the for loop is only a single line of code.


Example

for %i 1 20
{
	msg %i $
	wait 10
}
halt

  • Flow control commands allow scripts to make decisions based on the evaluation of boolean expressions.
break Jumps to first statement outside of loop
call Transfers execution to another script file
continue Jumps execution of a loop to next iteration
exit Exits a called script
for Creates a counting loop
gosub Transfers execution to the matching sub
goto Jumps to another part of the script given by a label
halt Stops the script
if Executes code based on the evaluation of an expression
pause Temporarily stops the execution of the current script
repeat..until Creates a loop that checks condition after execution
return Returns from a sub
stop Ends the script
while Creates a loop that checks condition before execution
