AutoHotKey how to pass/evaluate parameters to functions

autohotkeyparameters

I'm having trouble understanding how parameters are accessed in AutoHotKey functions.

For example, I set myVar variable with the InputBox, then pass it to a function. How do I evaluate the arg in the TestFunction?

#t::
    inputbox myVar, What is your variable?
    myNewVar := TestFunction(%myVar%)
    MsgBox %myNewVar% 
    return

TestFunction(arg)
{
    MsgBox arg
    msgBox %arg%
    return %arg%
}

What I'm looking to do is setup a hotkey that will prompt for a keyword for an app, then evaluate what is entered in the function and fire up whatever app corresponds to that keyword.

Thanks!

I've corrected your script (like Bavi_H suggested) and added an example to launch an application corresponding to a keyword.

#t::
inputbox myVar, What is your variable?
myNewVar := TestFunction(myVar)
MsgBox %myNewVar% 
return

TestFunction(arg)
{
    msgBox %arg%
    if (arg = "calc")
    {
        run, calc.exe
    }
    else if (arg = "word")
    {
        run, winword.exe
    }
    return arg . "bob"
}

Autohotkey – problems when using if, else if statements inside Functions

I have problems when using if, else if statements inside Functions they don't recognize my vars, despite I have set them to global at the beginning of the script...

You believe that the problem is to do with if/else if statements, however the evidence points to problems with local/global variables.

You need to define a variable as global, within a function in order to refer to the global version of the variable (rather than the local version of the variable).

Example code:

^q::
vText := "hello" ;the global version of vText
Func1()
Func2()
Func3()
Return

Func1()
{
MsgBox %vText% ;the function's local version of vText is blank
Return
}

Func2()
{
global vText
MsgBox %vText% ;the function uses the global version of vText
Return
}

Func3()
{
global
MsgBox %vText% ;the function uses the global versions for all variables
Return
}

Note:
The 'if' lines should be of the form:

If (AR4toolCur = "Selection")

not:

If (%AR4toolCur% := "Selection")
