Synopsis

call {file} [parameter...]

Description

call command will transfer execution to another script. It will run the script until it meets the exit command or the end of the file.


Note: Right now EasyUO doesn't really support strings. Therefore, CALL won't work if the path to a file contains any spaces. Use the DOS short filename syntax to get around this problem.


wrong: C:\My Documents\blabla.txt


correct: C:\MyDocu~1\blabla.txt


Example

call subs.txt recall %runebookid %runenum
halt

Note: call arguments handling work exactly the same as goSub command. Thus, %0 will hold the number of parameters passed, %1 will hold the first argument passed value and so on. See exit command page for more infos.

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
