Is there a function or type definition in the standard library for a string type? Basically, I just want to distinguish between "this is a string" and { "this is a string" }, one of which is a string and the other is a sequence of strings.
If there is not yet one, I would suggest at least an all_atoms() function, which returns True if all elements of the sequence are atoms.
-- Thats easy to determine include std/sequence.e procedure check(sequence s) if atom(s[$]) then puts(1,"It is a sequence\n") elsif sequence(s[$]) then puts(1,"It is a sequence in a sequence\n") else puts(1,"Do not know ?\n") end if end procedure sequence s1 = {"abcdefghi"}, s2 = "abcdefghi" check(s1) check(s2) if getc(0) then end if -- pause
