Hp 50 ; ± What's behind that command/program?
About Palindrome last post

I tried "123" ±, but did no get the reversed string.
What is the program "hidden" behind ±?

Thanks

It's there in Peruna's post (#14).

Code:
'±' #7F80h 48. bytes
«   DUP SIZE { DUP HEAD SWAP TAIL ± SWAP + } IFT
»

On the 50G, you can replace it with the command SREV when Library 256 is attached.
