A shorter Pause (PSE) in a program

[rprosperi]

I didn't examine stack use/needs in the provided program at all; SDEV/RDN was only used as an example of relatively slow commands to take up the desired amount of time. But as noted and inferred above, a series of more obvious commands like X<>X will likely be easier to insert without stack juggling and will certainly be easier to understand a year from now.
