Oops! One more try. Fabio's code gives 2 results from 2 separate lines of code. In his test, he gets 1088 and 1088 (I presume run in the IDE). I get 0 and 0 either as IDE or as Exe.

>>Just for the record David, I did it both ways. Running a prg from inside the IDE, and as an exe. I got the same results both ways. I should also point out that the help file is wrong. It says 'returns numeric', but in fact, it's a char. Try ? Vartype(sys(1104)).
