Goto

Synopsis

goto {label}

Description

The goto command moves the execution to another part of the script. The destination point is given by a label.

Note:

Don't goto out of a sub. Always use return! EasyUO will probably not crash but it is VERY bad programming style. A label in the code must be followed by a colon, where as gotoing to the label does not require a following colon. Inline comments do not work with labels in EasyUO 1.4.

Example

loop:
if %donotloop
	goto exit
goto loop

exit:

Simulating a Switch Statement

Switch structures (like seen in C/C++) can be simulated in EasyUO using the goto statement:

set %a #random % 3 + 1
goto case , %a

case1:
  display ok One
  goto case_exit

case2:
  display ok Two
  goto case_exit

case3:
  display ok Three
  goto case_exit

case_exit:
halt

Flow Control

• 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
