Hello! I have solved the file problem.

It is in fact a bug in GPC 2.6.3: The bind procedure does not add a null character to the filename string when passing it to C. But no problem: we can correct it manually. (Since often there is a null character in RAM following the string by random, the error was not always reproducible.)

The following modified Assign procedure does work around the bug and has been proven to work with GPC:

Procedure Assign ( Var T: Text; protected Name: String );

Var B: BindingType;

begin (* Assign *) unbind ( T ); B:= binding ( T ); B.Name:= Name + chr ( 0 ); (* add the null character manually *) bind ( T, B ); B:= binding ( T ); end (* Assign *);

According to Berend de Boer:

If you can repeat it, compile with another Extended Pascal compiler, for example Prospero's one. If that fails too, there is really something wrong with the code. But I suspect gpc. You're using which OS?

I am using Linux, OS/2 and (Novell) DOS.

I have never seen a compiler for Extended Pascal ... is Prospero's one FreeWare? Where can I find it?

Greetings,

Peter
