Wow, this is neat.  Now we can select & unselect one item, or many items,

 It *is* pretty neat.  Unfortunately, I think that it's a case of "too
little, too late", since they could have integrated this into a real GUI,
but that's for a bygone holy war...

1) I tried your code and things seemed to work nicely here.  Your subfile
starts on line 6.  Is it possible that something in lines 1 thru 5 are
causing troubles?  I saw no turquoise at all.

 They use Rumba here (at least for now).  Maybe that's the cause of the
weird colors combo.

2) I didn't try changing colors beyond the defaults provided for the various
values in the SFLCHCCTL field.  I did notice the following in the manual:
The CHCAVAIL, CHCSLT, and CHCUNAVAIL keywords can be used to indicate the
color of the items within the selection list, when the list is displayed on
a color display station. The CHCAVAIL keyword indicates the color of the
items within the list which are available for selection. The CHCSLT keyword
indicates the color of the selected items. The CHCUNAVAIL keyword indicates
the items on the list which are not available for selection. These keywords
can be used in a subfile control record only if SFLSNGCHC or SFLMLTCHC
keywords are also used."

 I'll have to play w/ the CHCAVAIL and CHCSLT keywords to see if I can
make it do what I want.

3) because of the way that the field changes color when its selected, I'd
suspect adding more than one visible field to a subfile might be confusing.
 As easy as it is to concatenate fields with EVAL now though, is this
really a problem?

 Not at all.  I just found it surprising.  It does mean though that if I
want to add some attribute to the field I would have to do it manually via
hex attributes, which is less than desirable, IMHO.
