Both Michael and Haje are correct that one can use a case statement
for this sort of thing. But IDL handles a series of if statements just
fine, too:

pro demo, arg

if arg eq 1 then begin
print,"one"
endif else if arg eq 2 then begin
print,"two"
endif else begin
print, "many"
endelse

end

This requires typing a lot more characters than the case version,
but I think it can sometimes make the program logic a bit clearer.
Either way works, so feel free to use whichever idiom you feel more
comfortable with.
