Having just gone through the exercise of attempting to convert 3298's SysRPL code to UserRPL, I can definitely see the advantage of a reverse POS, and I think the SysRPL parameters for both POS$ and POSCHRREV equivalents would be good (namely, being able to choose the starting position for the search).
