[Gambas-user] ByRef

[Emil Tchekov]

Forgot to gave you example (VB)


sub main()

	dim a as integer

	a=1

	debug.print a, pr1(a)
	debug.print a, pr2(a)
	debug.print a

end sub


private sub pr1(byval a)

	a=2

	return a

end sub


private sub pr2(byref a)

	a=2

	return a

end sub


result will be as follows

1   2

1* 2

2 (!)


*As you can see on the first sub the var a is local to your sub, it was
changed (returns 2), but the passed a has stil value 1

(!) in the second procedure the passed var a was changed! (the a that was
defined in the sub main!)

Hello List!

I've switched to development version 3.0 and I'm trying to get rid of this
ByRef thing. I wonder, if someone could explane the syntax to me!

Thanks in advance!!
