Using the "or" operator with filter

[Roger Eller]

Thanks Richard.

To give a better picture of the requirements, the gCodes will be read from
a user editable preference file (.txt), so there could easily be 3 or more
(or less) items that have to be examined for each line of tList (a report
file).

At the moment, it works for the hard-coded 3 gCodes. That's why I tried
"or" in hopes of filtering them all in a single pass. I'm going to build a
smarter repeat that can adjust to the  number of items in gCodes.
