[Gambas-user] gb.args - a question

[Willy Raets]

Hello,

I'm experiencing some trouble implementing gb.args
I made a small testcase named Arguments.

To implement version and help are no problem :)
Now I try to add an argument a (about)

Goal is that:

Arguments -a 
OR
Arguments --about
RETURNS
To test gb.args in GUI application

The code I have is below. I'm not getting any wiser reading the
documentation over and over.
I have tried several different things, ended up with this. But the new
argument still doesn't work.

---- Code module Start (starup class)----

Public Sub Main()
  
  Dim sAbout As String
  Args.Begin("Arguments <options>")
  sAbout = Args.Get("a", "about", "To test gb.args in GUI application")
  Args.End()
  Print sAbout
  FMain.Show
  
End

---- End Code ----

Results in terminal:
1. For: Arguments -h

Arguments <options>

Options:
 -a --about                             To test gb.args in GUI
application
 -V --version                           Display version
 -h --help                              Display this help

2. For: Arguments -V
0.0.1

3. For: Arguments -a
Arguments: argument missing for option -a

How do I get this -a to work? What am I missing?
Any suggestions or a small example would do miracles.

Thanks,

Willy
