console only OR screen only

[mdijkens]

I'm building a small console utility.
If a parameter is given, the utility should run in the console and print the result there.
But if no parameter is given, a screen interface should be shown where user can enter parameter(s) and play with result.

This basically means, I want console:only when command$<>"" ELSE Screen:only

Code: (Select All)

$Console

If Command$ <> "" Then

  _ScreenHide

  _Console On

  _Dest _Console

Else

  _Console Off

  _ScreenShow

  _Dest 0

End If

Print "this is it"

If I run this program a very brief flickering can be observed in both cases:
- when doubleclick the exe, I see briefly a console window before the screen is shown and console window disappears
- when at commandprompt including parameter, a screen briefly comes up and disappears. (brief window focus change)

Anyone a good idea/approach to have 1 and only one of them from the very first beginning?
