This trick does work in Javascript because it is purely and slowly

Some guy once said that checking whether the syntax of a C source is
valid is equivalent to the Touring machine halt pr
C programs so
that they are not nearly undecipherable as usual, but totally

I don't believe there is a way of performing macro substitution in S*BASIC
programming. Now, it can probably be implemented in one form or another.
The most obvious is a pre-processor that takes a macro and expands it
before the program is actually sent to a compiler or parser. C has a

Hi all,
I've been using Foxpro v2 (programmable database system) for several
years now and 'macro substitution' is one of those powerful functions I
use a lot in my programmes. I wonder whether such a function is
available (possible?) in Sbasic.
Here's an example of a 'macro substitution':
