And here's a real solution. :)
if match("EOF", s) = 1 then
[alpha]
else
[gamma]
end if
If the first 3 letters are EOF, then do alpha, otherwise, do gamma. My
first attempt used find(), and won't work. Also, if it had match()
instead, it still wouldn't work like you wanted since it didn't have =1
(If it found it at all it would do alpha.) Remove the = 1 to have it
always work if it finds EOF anywhere in s. See, simple. :)
