HHC 2017 RPN Programming contest information and results thread

[Didier Lachieze]

My current RPN program is 65 bytes including 1 register (7 bytes).

EDIT: down to 62 bytes after a few changes.
EDIT 2: I forget rule 6 and need to add 9 bytes for LBL HAPPY... So with a few optimizations it's now at 70 bytes including the END instruction.
EDIT 3: well, after following all the rules (I hope so) I'm at 75 bytes, with a program starting with LBL HAPPY and restoring all defaults settings before ending with a regular END.
