Hello! According to Michael Meeks:

PROCEDURE print_str (name: PACKED ARRAY [lo..hi: integer] OF Char) ; {a} [...] It compiles to object fine with the {b} labeled code in, but the {a} labeled code causes a crash :

This is a bug in gpc-2.0 or below which has vanished in recent beta versions. To get a GPC without that bug, download gpc-970714.tar.gz from ftp://agnes.dida.physik.uni-essen.de/gnu-pascal/beta/.

Is this perhaps one section of the ISO 10206 spec. that isn't implemented yet ? or am I doing something extremely daft :-)

It's part of level 1 of ISO-7185 Standard Pascal.

TYPE ulong = 0..16#FFFFFFFF ;

Also, gpc-970714 can compils this. In addition, it has an extension type `Cardinal' or `Word' (two names) which has the same size as `Integer' but is unsigned. As another extension, you can write `Cardinal ( 32 )' to be sure to get an unsigned integer type of 32 bits width. (`Integer' may actually have 64 bits or whatever on some machines.)

Thanks in advance for any help, its a great project, keep up the good work.

Thank you as well for your interest. Yes, we'll try to keep it up. :-) If you want to contribute to the project, too: You seem to have some experience with Extended Pascal. When we will face 100% compliance to Extended Pascal in the future we will need some test programs urgently, and useful and/or entertaining example programs and documentation are very welcome, too.
