Variable conformant arrays, and the price of fish..._(re)

Hello!

According to Michael Meeks:

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/.

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

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.)

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.

Hope this helps,

    Peter

PS:  What has all this to do with the price of fish?
