--- Comment #2 from Jean-Pierre Ledure <j...@ledure.be> ---
Consider next code:
sub foo(Optional a, Optional b)
MsgBox IsEmpty(a)
end sub
sub bar
foo(b := 1)
end sub
- (1) The message box returns True without any option, or with Option
Compatible
- (2) A syntax error is displayed with Option VBASupport 1
In other words when (1) and the call uses the := syntax, the skipped arguments
contain Empty, not "Missing". Empty means something in this matter.
That's the reason why in ScriptForge, everywhere I test the presence of an
argument to set a default value (hundredths of times ...) I use the
construction
If IsMissing(a) Or IsEmpty(a) Then a = ...
Please do not change the actual behaviour without good reasons.
