50G RPL Question

[DavidM]

If you wish to have the program delimiters included, the following adds those to the beginning and end of the program:

Code:

\<<
   \->LST
   \<< \>> \->LST LIST\-> DROP
   ROT SWAP
   + +
   \->PRG
\>>

Likewise, the following converts a program object with the program delimiters back into an algebraic:

Code:

\<<
   \->LST
   DUP SIZE 1. -
   2. SWAP SUB
   \->ALG
\>>

Joe's warning still applies -- watch out for 'Invalid Expression'.
