As is often the case, I use a lot more code to do simple things than is probably necessary. Sometimes I figure it out and reduce the number of lines considerably – sometimes not. Here's a much-simplified example used to populate legends on graph. A combobox selects the "scale" for different legends.
if yscale = 1 then
#plot.100, "down"
#plot.100, "place 1 12; font arial 9"
#plot.100, "\ $100 "
#plot.100, "delsegment plot.100"
#plot.100, "flush plot.100"
#plot.50, "down"
#plot.50, "place 1 12; font arial 9"
#plot.50, "\ $50 "
#plot.50, "delsegment plot.50"
#plot.50, "flush plot.50"
#plot.0, "down"
#plot.0, "place 1 12; font arial 9"
#plot.0, "\ $0 "
#plot.0, "delsegment plot.0"
#plot.0, "flush plot.0"
end if
if yscale = 2 then
#plot.100, "down"
#plot.100, "place 1 12; font arial 9"
#plot.100, "\ $200 "
#plot.100, "delsegment plot.100"
#plot.100, "flush plot.100"
#plot.50, "down"
#plot.50, "place 1 12; font arial 9"
#plot.50, "\ $100 "
#plot.50, "delsegment plot.50"
#plot.50, "flush plot.50"
#plot.0, "down"
#plot.0, "place 1 12; font arial 9"
#plot.0, "\ $0 "
#plot.0, "delsegment plot.0"
#plot.0, "flush plot.0"
end if
And so on …
The code works fine, but with over 9 legends per 5 scale selections, it seems kind of repetitious. So, I'm once again risking embarrassment to see how you experts would go about it. Thanks!

Thanks Walt, but I don't understand (Tag$, Txt$).

Now that I've read, reread, and reread about "FUNCTION," I have a better understanding and the code you supplied is working!!!
So now I have another simplification question.
For yscale = 1, yscale = 2, through yscale = 5, the digits after the "\ $xxx " are multiplied by 2 for each scale: $100 for scale1, $200 for scale 2, $400 for scale 3, $800 for scale 4, and $1000 for scale5.
Rather than repeating
RetVal = FN.DoNum("#plot.100", "\ $200")
RetVal = FN.DoNum("#plot.50", "\ $100")
RetVal = FN.DoNum("#plot.0", "\ $0 ")
for each scale, is there some way to multiply the numbers contained in "\ $xxx"
(There are actually 9 "\ $xxx" for each scale), so the code is still rather lengthy.
(Plot.100, plot.75, plot.50, etc. relate to graphicbox locations and aren't issues.)
I hope this makes some sense, but thanks for your help anyway!

Is this what you mean?
"\$0" X 2 = 0
"\$50" X 2 = 100
"\$100" X 2 = 200

Kind of. As in your example:
"\$0" X 2 = 0
"\$50" X 2 = 100
"\$100" X 2 = 200
I'd like to substitute the yscale number for the X 2, but that only prints what's between the quotes.

I think this is what you want, but not sure. I have changed the function and commented it so you might understand better what is happening in the function. Now it only has to be called once for each value of yscale. NOT TESTED '
RetVal = 0
Value = 0
SELECT CASE yscale
CASE 1
Value = yscale * 100
RetVal = FN.DoNum("#plot.", 100, Value)

RetVal = FN.DoNum("#plot.", 100, Value)

Actually, the above will not produce what you want since in your example for yscale = 2 you do 200, 100, 0. If for yscale = 3 you do 300, 100, 0 the function would have to revert to the original and call it for each value.

Here is a slightly different approach based on what I think you want. It uses the same one-shot function but with slightly different input.
NOT TESTED

RetVal = 0
Value$ = ""
SELECT CASE yscale
CASE 1
Value$ = "100, 50, 0"
RetVal = FN.DoNum("#plot.", 100, Value$)
CASE 2
Value$ = "200, 100, 0"
RetVal = FN.DoNum("#plot.", 100, Value$)
CASE 3
Value$ = "300, 100, 0"
RetVal = FN.DoNum("#plot.", 100, Value$)
END SELECT
