declaring a variabale as string type
Post 302489899 by Scott on Saturday 22nd of January 2011 10:29:47 AM

Hi.
Functions only "return" integers ("return codes") (and those are only represented in 8-bits). And return is not a variable.
Variables aren't "typed". They all contain strings. You can notionally alter this behaviour using typeset, but that would only affect what you could assign to that variable, or how it is represented.
It's common to assign the "return string" to a variable within the function before the function terminates.
I never use C-shell. so please post the "function" so we can have a look
