Hex Compiling

Hi,

What is the way to compile Hexadecimal numbers with Qliberator and SMSQ/E.

SMSQ/E can display hexadecimal numbers prefixed with a $ symbol.

Unfortunatley, Qliberator gives an error when trying to compile the statement.

Strangely enough, Turbo compiles this with no errors and works as expected.

Derek,

There's an utility somewhere on Per's site (just recently re-opened), I believe, that replaces all hexadecimal constants in S*Basic programs with decimals for compilation. Should come in handy here.

(Thus, this is a just-in.time question)

Why not use HEX command?

You can use that. But if you have a lot of these hex constants in a program, this might
  1. be quite some work
  2. be slow (runtime-wise): QLiberator is not smart enough to see that HEX("<constant>") is still a constant and uses valuable time to do the conversion at run-time. Replacing the hex constant with a "real", numerical constant is much faster

Yes, I've found it here ... http://www.knoware.no/
It can be found under ENTER / GO SUB / DeHex
It looks like a very neat procedure.

Regarding Turbo, I note that it's not possible to compile a $0 or %0.
Those cases would have to use a plain 0.
