Your brain fart got me thinking, Ward. I neglected to tell you that the slash at the end of a line could be due to a deleted X, Y or Z, which would mean I would have to have a space after every slash, not just before the Z.
But, good news, you set me on a slightly different track that seems workable.
Here was my old RAPID LINE FORMAT G00:
{G}{X} {G}{Y} {G}{Z}, where the code {G} was given a prefix of / instead of G
Here is the new one:
{{G}{X}} {{G}{Y}} {{G}{Z}}
Now, with coordinates modal ON, every instance of a solitary / appears as:
{/} {/} {/Z1.2345}
or
{/X1.2345} {/}
no matter if it is at the end of a line or not. These are all quickly and easily deleted.
However each rapid move is also enclosed in {}, so the code looks like this:
{/X1.6717} {/Y-1.2318} {/Z0.2}
Again, a double application of find and replace all removes first the "{" and then the "}".
Thanks for the insight that got me on track
