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.
|
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.

| 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 |
