Hi, I'm setting out to replicate some parts of Psion programs that I wrote, using their version of Basic called "OPL". Like in many languages a numeric constant could be set to a hexadecimal value by prefixing (with "$"). Is there an equivalent in Basic4PPC? (I cannot find it in Help.) (Since I am doing binary serial data transfer with a Garmin GPS, see Psion programming projects, it would be particularly pertinent.) Cheers, Mike.
