optional func parameters

[masonje]

I want to create my own runwait function to add some options, but I can't figure out how to create optional parameters.

_runWait("file" [, working dir [, flag [, i/o flag]]])

How do I make a pass in variable optional?

The second parameter is optional and is by default 1.

Func Add($a,$b=1)
       Return $a+$b
EndFunc

[GaryFrost]

Func _MyFunc($s_text, $myflag = 0)

; do something here

EndFunc

$myflag would be optional

Rock! I see that now in the help, but it didn't sink in....dork

question 2. is there a way to not have to put quotes around the "@SW_HIDE" option? As is, the _runWait() func goes to Else if I don't quote around the option.

_runWait('net start "Automatic Updates"', "", "@SW_HIDE")

Func _runWait($r, $w='', $f='', $sf='')
    AutoItSetOption("RunErrorsFatal", 0)
    Select
        Case $sf <> ''
            $pid = run($r, $w, $f, $sf)
        Case $f <> ''
            $pid = run($r, $w, $f)
        Case $w <> ''
            $pid = run($r, $w)
        Case Else
            $pid = run($r)
    EndSelect   
    
    if @error Then
        MsgBox(48, "Error", "Error running " & $r)
        Return "error"
    Else
        ProcessWaitClose($pid)
    EndIf
    AutoItSetOption("RunErrorsFatal", 1)
EndFunc

BTW

The only reason I'm doing a new runwait is b/c runwait doesn't always seem to stick. That and I want to be able to add some options...and learn more functions.

Instead of all those Case's I think you can without any problems just make

your function pass on the default values that your function uses, and for the

third parameter you can just use @SW_SHOWDEFAULT as the default value.

Also note that there is a macro called @NumParams which could have helped

you if you choose to keep the Case's, however it's not needed in this case.
