Define osc 8 not working on 12f683 - wondering if Its related to include files?

[dw_picbasic]

Actually, I'm using Micro Code Studio editor and it auto-magically changes the case of everything to what it likes.
So I tried typing all upper case and MCSE just changes it to lower case.
I've looked in the PBP3 manual and don't see anything that would give a hint.
I think I'll try to email Mel Labs if they have the time to answer.
I'm sure they've seen that before.
They designed the compile code, so I would hope they would know what I should be looking for.
I wonder if there is something in the include file that is over-riding the define statement.
I'll post what I find out.
Thanks my friend :-]

Hi,
Actually, you can change the way MCSP formats the code by going to View -> Editor Options -> Highlighter but that can be a bit misleading because it's actually only how MCSP displays the code on the screen IN MSCP, if you open the code in Notepad or whatever it'll be exactly as you typed it - something to watch out for in other words.

If you look at section 2.3.3 in the PBP3 manual you'll find

For the user familiar with Assembly Language, the major clue to understanding is that DEFINEs in PBP are converted literally to Assembly Language #DEFINE directives.
For the practical PBP user, there are a couple of fundamental points to consider:
1) DEFINEs are CASE SENSITIVE!
2) Specific DEFINEs are generally associated with PBP commands. The command pages will describe how the relevant DEFINEs affect the operation of each command.

This has been covered multiple times in the forum but again, the word define is a PBP command/keyword and PBP is not case sensitive so it can be either case DEFine, defINe, DEFINE, define, doesn't matter. What comes AFTER DeFiNe is passed directly the assembler and the assembler (MPASM) IS case sensitive. PBP's library routines are written in assembly and uses the OSC setting/value/variable/definition/whatever to calculate software delays, baudrates etc etc etc. So when you need to tell the compiler that you're using another oscillator frequency you need to define OSC not osc or Osc, they are three different things and the library routines only know about OSC - not osc or Osc.

/Henrik.

As many times as this DEFINE in particular gets brought up you'd think MeLabs would at least give you an error during compile if the two defines XXX don't match. Seems like it should generate some kind of error.

You can DEFINE anything you want for use with your assembly language routines.
PBP has no way to know if you are using 'osc' in your routines, or if you didn't capitalize 'OSC' for PBP.

It is unfortunately up to you to get it right.

Never good to rely on lowest common denominator. That reliance means this thread will be recreated many more times.

Henrik was right in his original post on this.
It just occurred to me ***DUH*** that just because the editor automatically makes "define" into lower case, doesn't mean the OSC is supposed to be lower case as well.

With MicroCode Studio the only syntax that works is "define OSC 8"

Nice to have the 8mhz clock running for more fun experiments.
BTW:
I just got a couple 18F2550 chips.
Looking forward to playing with them!!! :-]
