CONST limitations (page 216)

[RCO]

Issue with CONST

I notice the following:

You can't use data types above 16 bits.

This is in contradiction to page 216 of Reference manual:

... may be used with any data type ...

I also get garbage during debug for table values. This applies to global and local.

Comments?

[PCM programmer]

Debug with what IDE, CCS or MPLAB ?
What version ?
What version of the compiler ?

Post a small (very small) program that shows the problem.
Describe the steps taken to see the problem.

Debug with what IDE, CCS or MPLAB ? : CCS
What version ? :

IDE: 3.40
PCB: 3.180
PCM: 3.180

What version of the compiler ?

PCW Compiler: C Language

Edits:
1: Part of the issue was the size of the Table (apparently there is a 256 byte limit). If the ceiling is observed, 32 bit types are OK

2. I do still get garbage on mouse overs and watches for table elements.

3. for timmy and TIMES1 I get nothing on mouse over. This is before and after running to a breakpoint.

The CONST size is apparently 8 bits.

[PCM programmer]

Your "int16 CONST TIMES1" array initialization code has five values at
the end that are larger than an int16 variable can hold.


It's possible that vs. 3.180 of the IDE had a bug in it. The comment
that CCS has in their old versions page, that's near to your version, is
this one:

[RCO]

Yes, I am aware.

I will test the catch-all. How do I upgrade?
