What I think he means is this:

constant  LA_up= "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
constant LA_lo = "abcdefghijklmnopqrstuvwxyz"
constant LA_diff = LA_up - LA_lo

global function case_LA(integer c, object x)
    integer n
    if atom(x) then
        if c then
             n = find( x, LA_lo )
             if n then
                  x += LA_diff[n]
             end if
        else
             n = find( x, LA_up )
             if n then
                  x -= LA_diff[n]
             end if
         end if
     else
         for i = 1 to length(x) do
             x[i] = case_LA(c, x[i])
         end for
     end if

      return x
end function

Works for any alphabet and code page, and is faster, because it
doesn't have to keep slicing the alphabet sequences.

The limitation of the above function is that LA_up and LA_lo must be
the same length... what do you mean by 3 extra letters? What if you
try to convert them to lower case? If it should just leave them as
upper case, that's fine - just leave them out of the function.

nuclear reactors, medical life support systems, or anywhere where
failure may cause injury***
