You can use "-1" instead of getting the last char to shorten it a tad.
When in doubt you can often use parentheses to make things explicit for
put (char -3 to -1 of (line 1 of fld "result")) into tLast
The outer-most parens are probably overkill, but in general parens are
useful not only for the compiler but sometimes for aiding readability
too. The outer parens make it clear what's being "put", and the inner
parens help break the first parsing operation from the second.
Let me know if that doesn't do it and we'll look into it more.
