I recently purchased an HP 48GX. I have downloaded several Libraries of Engineering programs from the Web and found them very useful. I am interested in writing some of my own programs in RPL. The only calculator programming experience I have is with HP11C, 32SII and with Elektronica MK 61 calculators which basically use just "keystroke" programs. I have been away from computer programming for a long time, but at one time was very proficient in FORTRAN, BASIC and PASCAL languages.
I am looking for a good text book or manual which gives more instruction in programming in RPL Language than is offered by the HP 48GX Owners' Manual. Does anyone out there know of such a book; and just as importantly where I can obtain a copy? Thank you.
Wayne.
