Non-local exit out of method
by Peter Schorn 10 Mar '06

10 Mar '06

Dear all, are there any plans to make non-local exits out of a method legal? This works in CodeWarrior Pascal and looks somehow better than a goto. The following program illustrates the issue: I could not find a way to make a non-local exit out of q using the exit statement. program exittest; { compile with gp --nonlocal-exit exittest.pas } type o = object procedure p; end; procedure o.p; procedure q; begin exit(p); { error: invalid … [View More]

Changing source code
by Prof A Olowofoyeku (The African Chief) 08 Mar '06

08 Mar '06

Hi This isn't strictly a GPC question, but it is related, so I'll ask anyway :| Is there an easy way to change a string in all source files to another string? For example, if I want to change all occurrences of "Type foo = Object (bar)" to "Type Tfoo = Class (Tbar)" in all ".pas" and ".pp" files in a directory tree, is there an easy way to do it, using standard GNU tools? I could of course write a program to do it, but I figured there could be an easier way. Thanks. Best regards, The … [View More]

Reading source past end of block
by Pascal Viandier 04 Mar '06

04 Mar '06

I encountered an unexpected error with GPC when compiling a Pascal source that contains "some text" (not Pascal code) after the final "End." of the program. GPC tries to compile this extra text and finds syntax errors in it. Although I did not see any reference to this in ISO 10206, I think it could be a nice feature for GPC to ignore everything after the final "End." in a program or a unit since nothing useful for it should be there. I am using gpc 20050331 under Debian Linux X86 and gpc … [View More]

GPC with GCC 4?
by Silvio a Beccara 03 Mar '06

03 Mar '06

Dear friends, I haven't been following the list very closely lately, so I'd have a question: is there a version of GPC which is based on GCC 4? I'm asking because I've been told that GCC 4 is much faster than its predecessors, so there could be a significant gain in performances.

Unit name same as exported procedure name not allowed
by lanceboyle＠qwest.net 01 Mar '06

01 Mar '06

I have a unit named Head which exports a single procedure also named Head. In the calling program, the compiler (20050331) generates an error, "statement used as expression." The docs don't seem to say anything about a name limitation. Have my previous two Pascals let me get away with something naughty? Of course, renaming either the unit or the procedure fixes the problem. Jerry

However, that problem notwithstanding, the debugger continues to behave oddly. After the debugger loads, my program takes about 10 seconds before anything appears to happen with it. Then, stepping in/out/over is unreliable, with the "program counter" (the red arrow that indicates which line is about to be executed) pointing to … [View More]
