Occasionally, you may need to move or copy a range of lines in reverse order. Previously, there was a FILTER program to do that, but with the advent of macros, it can be done a little nicer as line commands.
The CR/CRR line command will copy a line range after an A point or before a B point, in reverse order.
The MR/MRR line command is like CR/CRR but deletes the line range afterwards.
As usual, no guarantees, but so far it appears to work as advertised.
Let me know how you like it or if you run into any issues.
