Convert the program to a string with →STR, modify to your heart's content, and then convert back to a program with OBJ→. This has the advantage that it forces a recompile of the program so that your changes are guaranteed to take effect.

Edit: I think I'm mis-remembering the compiling thing, which only applies to algebraics.

That should work in most cases, including this one, but if the program has any non-UserRPL stuff in it, e.g. takeovers, externals, etc., then recompiling it from the string representation will probably either fail with an error, or store a broken program.

I could swear I saw some method to build/modify a program on the fly without doing any string conversions. Can't remember where I saw it, though. It may have been an algebraic-to-RPN converter, unless I'm imagining the existence of that too.
