Hi:

  this must be a FAQ, but let me ask. How can I treat
a CP varaiable as an unsigned number, such that I can
easily converse with C libraries?

Specifically, the following does not compile with a message
"number too large", even though it would fit as an unsigned
bit pattern in the BYTE variable.

Any idea how to make it compile without violating the "CP spirit"
in some major way?

MODULE TestTest;
PROCEDURE TEST;
        VAR test:BYTE;
BEGIN
        test := 0ABH (*number too large*)
END TEST;
END TestTest.

As a side remark, lack of unsigned numerics in CP looks
like a major pain to me. I did not realize this until started
interfacing CP to Windows DLL's.
