This is good advice, and to clarify further...
If this works...
myButton whenActivatedDo: [LibC system: 'a.bat 10'].
and this doesn't...
myButton whenActivatedDo: [LibC system: 'a.bat', myTextField asString].
and you can't see why, then you likely have an assumption about what
you think is happening, that is blinding you what is actually
happening, which you need to expose :)
i.e. you need to know *exactly* what string is being passed in the
#system: call.
One way to do that is to replace "LibC system:" with
"Transcript:show:" in your code.
cheers -ben.
myButton whenActivatedDo: [ Transcript show: myTextField text]
