Hi the list.

I am now running what I think is the up to date gpc version:

971001(2.7.2.1) (documentation of 970714)

(why is the name now xgpc?)

Except my misunderstanding of something, the followings are types expected to be supported by the brand new GPC:

(signed) (unsigned) (signless) GNU C equivalent typical size (bits)

ByteInt ByteCard Byte [un]signed char 8 ShortInt ShortCard ShortWord [unsigned] short int 16 Integer Cardinal Word [unsigned] int 32 MedInt MedCard MedWord [unsinged] long int 32 LongInt LongCard LongWord [unsinged] long long int 64

But none of them is accepted by the compilator (except Integer, and may be few last I haven't tested, but ByteInt, ShortInt, MedInt, LongInt, ByteCard, Byte, Shortcard, ShortWord and Word does not work, for the others, I don't know but I bet they do not work as well).

That a type "does not work" means that in my source if I put

var i, j : byte;

then GPC will yell at me:

laussy@localhost /home/laussy/conway 18:17:35 Sun Mar 1 20$ gpc --version 971001(2.7.2.1) laussy@localhost /home/laussy/conway 18:18:19 Sun Mar 1 21$ gpc byte.test.pas byte.test.pas: In function `program_Test': byte.test.pas:3: type name expected, identifier `Byte' given

The same for the others.

If I keep the old type definition:

type shortint = __byte__ integer; byte = __unsigned__ shortint;

then the byte algebra is still bugged, with for example and absolute value of (2-4) given to be 252!

Besides, in the doc, one can find:

* The Run Time System (RTS) does not know about modified types such as `__byte__' or `__unsigned__ Integer's or `__long__ Real's. Especially, you cannot `writeln' such variables.

Is it somewhat related?

Cheers,
