Would it take a lot to implement values in a #switch block, so that letters or
words could be used as selection criteria as well?

If not, or for the time being, is there a more elegant way to do this other than
a ton of #if ... #end's, or creating some sort of conversion index for the
strings?

This is not so ugly, compared to a #switch:

#if     (word = "foo")
     ...
#elseif (word = "bar")
     ...
#elseif (word = "baz")
     ...
#end

for letter, you can convert it to its code in the switch clause :

#switch(asc(Char))
#case(65)
...


No clue for words, sorry.

Yes, an excellent suggestion!   I will try to remember that.

Following your idea,
There's probably a way to generate a unique hash value.

Thanks as always   :)
