Rediscovering the HP50g after many years ...

[Joe Horn]

That "%%HP" line is only there to tell the HP50g that it's arriving (usually via cable) in ASCII format. The T(3) means that the "Translate I/O" mode is 3, and the A(D) means that the angle mode is Degrees. You can pretty much ignore that line.

I would suggest putting the program (in string form) on the stack, then deleting everything before the first \<<, and then using the resulting string as input to this program:

« 3 TRANSIO #2F34Dh SYSEVAL DROP OBJ→ »

This should convert the string into the original program object. Good luck!
