I've heard that using END is dangerous; what's the best way to end my program?

Compatibility:VB3 VB4 VB5

To end your program, use this code:

	dim ret as object

	for each ret in forms
		unload ret
		set ret = nothing
	next

What does it mean to pass by reference?

Compatibility:VB3 VB4 VB5

When you pass by reference, you get the actual variable. (You pass by reference by default.)

In contrast, when passing by value, you get a copy of the variable.

The net effect is passing by value prevents you from changing the variable

What is Option Explicit and why should I use it?

Compatibility:VB3 VB4 VB5

When you use Option Explicit, you have to declare all of your variables.

For instance:

sub mySub()
       dim i as integer
       i = 3                 'Works with either
       x = 3                'Works only when option explicit is disabled.
       ...
end sub

How can I break up long lines of VB code?

Compatibility:VB3 VB4 VB5

Use a space followed by a underscore, like this:

	debug.print "Hi! "; _
		"World!"
