GetNumber
The GetNumber function opens a dialog to request a number. If you click [OK], the entered number is returned.

number, bOK = GetNumber( number=nil, sPrompt=nil, sTitle=nil )
n is the initial value of the number. If nil, 0 is used.
sPrompt is the message above the number field. If
nil, a default is
used.
sTitle is the window title. If nil, a default is used.
If [OK] is clicked,
the function returns the number and
bOk=true.
If the dialog
is canceled, 0,false is returned.
All arguments are optional and assume default values beyond the last argument you specify. To use a default argument but follow it with a specified argument, use a nil in its place..
The window shown above was created using the following code. Note that the last argument, the window title, was omitted and left to the default:
number, bOK = GetNumber( 125.44, "Enter a number :" )
