Advice for getting started in RPL

[100LL]

Ok, I know I’m about 15 or 20 years late to the party, but I want to write a program for my 50G.

Really want to do it on my PC, make a library and put it on my 50G (and share it with the world too).

Can anyone give me the necessary steps, software advice, and how this actually works in practice. I work mostly on Linux machines and I’ve got 1 pc and 1 mac as well.

Thanks
