VID and code
[1/3] from: inetw3:mindspring at: 26-Feb-2003 10:14
Hello ML,
If someone would be so nice to help me
understand Rebol VID scripting.
I have some parses and functions
as a buttons' action... button "go" [ parses and functions ]
or button "go" feel [engage: func[if action = 'down
[ parses and functions]]]
but when i press it, the code works, but no other VID
(buttons, areas etc.) will work and i get script error...
** Script Error: Invalid argument: return
** Where: forever
** Near: if not parse facets vid-rules
how do i get a button to call my code without
returnning script errors ?
The docs available don't really talk about these things.
thanks in advance .

If you could post some actual code, that would help enormously. It can
be very hard to know what might be wrong with a bit of REBOL code
without seeing it.

That looks wrong, in that a function's format is...
func [arguments][code]
But as Gregg said, showing us the actual code that isn't working is
the easiest way for us to spot where the errors are.
