Excerpt of article text...
Last issue, we introduced this column with an overview of the similarities and differences between Microsoft Visual Basic (VB) and REAL Software's REALbasic (RB), concentrating mainly on their interfaces. In this installment, we'll concentrate on the back end: the code you use to make your programs work. I'll assume that you're already familiar with the interface of RB, and that you have at least a basic knowledge of VB's interface.
You'll find that overall, RB's implementation of BASIC is more strict in terms of syntax than VB. When I first started learning VB, I always religiously declared my variables (with "DIM" statements at the beginning of a block of code). VB users may be a bit concerned when they find that all variables must be declared. In recent versions of RB (after 5.0), the declarations do not have to be at the beginning of the code block, whereas they did previously. In turn, RB users who are looking into VB might find it strange that you do not have to declare variables in VB. There is a way to enforce declaration of variables in VB: put the line Option Explicit in the global declarations of the code for a form or module. However, this need not concern us here. The bottom line: in RB, always declare your variables!
