1. A sequence, by any other name
Hello all,
What I need is a sure-fire way to determine in my program if a sequence
is a character sequence versus a sequence of numbers. I need to
determine this dynamically.
Maybe this is a basic question? I dunno.

type string(sequence x)
return find(0,x > 255 and x < 0)
end type
it doesn't check if it's not a sequence though...

Oops, that should be
return not find(0,x > 255 and x < 0)

Depending upon the numbers involved, it may be impossible:
Consider, for example:
sequence s
s = {65,66,67,68}
puts(1,s) -- gives ABCD
? s -- gives {65,66,67,68}
Now, 64, 65... etc are perfectly valid numbers, but they may also be
valid characters. It's up to the programmer to keep track of what those
numbers are supposed to represent at any given time.
