If you have a string that is like this: ZZXYQPSPTABC

and you want to delete any occurrences of A, B, or C you could do this 
sort of thing:

Well; to make things easier for myself (i.e. so I had visual 
confirmation of things) I made
a stack with a fld "TEXXT" and  a Button "DO IT BABY".

I put "ZZXYQPSPTABC" into fld "TEXXT"

I put this script in button "DO IT BABY":

on mouseUp
    put fld "TEXXT" into TEXXT
    put the number of chars in TEXXT into CHNMB
    repeat CHNMB times
       if the last char of TEXXT is "A" then
          delete the last char of TEXXT
       end if
        if the last char of TEXXT is "B" then
          delete the last char of TEXXT
       end if
        if the last char of TEXXT is "C" then
          delete the last char of TEXXT
       end if
       put TEXXT into fld "TEXXT"
    end repeat
end mouseUp

try it.
