I can't compile this little program :

Program Bug05; Const XValMax : Byte = 125; Type T_XVal = Packed 0..XValMax; Var X : T_XVal = 64; Begin End.

Here is the output :

Reading specs from c:/djgpp/lib/gcc-lib/djgpp/2.952/specs gpc version 20000727, based on 2.95.2 19991024 (release) [...] Bug05.pas:8: constant out of range

??? For me it works ??? I have the same version of the compiler and djgpp

I don't understand what happened earlier today : now it compiles without problems. A possible explanation (?) : I write my programs under Windows, in a text editor, I have a lot of programs opened at the same time, and I run GPC in a DOS window : maybe the source wasn't fully saved... (but I made several tries...)

I suppose that you have indeed found a bug. To understand what is going on I have added a declaration

var Y: byte absolute X;

which enables to examine the binary contents of X. It is the same (at least for x=64) and all tests work as expected if you replace X by Y

???

I made another attempt : I wrote X into a File [ XFile : File Of T_XValue; ] : there is no problem, it wrote a byte with value 64 (40h). But I tried to read this value back into a program [ Read(XFile,X); ], the output is always the same [ 64 < 63 :-( ].

Unrelated P.S. Great thanks for your work on GRX. I downloaded it and installed it : everything is fine.
