This is not new to version 5.0, and is not special to byte
variables. I think that any typed variable has the same
problem. Of course, you would not be tempted often by non-scalar
variables. I have not seen or noticed this as a constraint
on "write" in the manuals, so you could consider it a bug.
On the other hand the work around is obvious:
... var x : byte;
...   x:=myconstant;
... write(myfile,x);

I have not tried the write with "typed constants" declared by
const x: byte=myconstant;
I suspect that this works, since now the compiler knows the
"type" of x.
