I'm trying to upgrade from gpc version 19991030 to 20010306 both based on 2.95.2 19991024 (released).

It looks as if 'class' has become a reserved word, which is unfortunate as it is a variable name our code uses frequently.

First question: is class now reserved in some way?

Yes (Delphi compatibility).

[snip]

I think it's only "conditionally reserved" (like many keywords from various dialects are). E.g., `var Class: Integer;' seems to work. But I'm not sure in which situations it works and in which it doesn't (optimally, in all those situations where it can't be confused with a class type declaration). Could you post some problematic example code?

Here's about the simplest case I can come up with quickly ...

test5.p ======= program test_class;

type tcomp=packed record name:string[80]; class:1..15; end; var comp:tcomp;

begin end.

I get: test5.p:5: parse error before `Class' test5.p:5: extra semicolon

...

Third question: any thoughts on whether there any other syntax changes I might trip over?

Have you checked the `News' chapter of the manual, in particular the first section and all items marked with `(@)' (as explained there)?

Yes, I've scanned it rapidly - I didn't find any mention of 'class' there (which is why I asked if there was anything else I might trip over), but I could easily have missed it.
