Thanks Waldek, That's a really big help. Having migrated from DEC Pascal which had very different MODULE integration syntax I had never picked up on the importance of the IMPORT clause, especially as the code has always compiled without a hitch. I wonder if there is any way gpc can pick up on the use of declarations which haven't been properly initialised, either at compile time or run-time? Regards, David Wood.

Frank,

I don't know if there is a bug number for this but I am attaching two really small bits of code which show it up. It's the only 'genuine' bug I have ever really come across in gpc. Basically, the globally defined string doesn't seem to get any length so whenever something is assigned to it, the contents vanish.

Your program is buggy: you forgot to 'import' your module. Even if you want to access objects in the module via external name you still need to 'import' it so its inititializer is run automatically. If you want main program to be in other language, then you need to call 'init_With_string' explicitly.
