Hello I have cygwin installed on my WinXP box and am loving it. However
I just noticed today that when I tried to use the local keyword in my
bash script it gives me the error "local: not found". The script works
on a RedHat box as expected so I would think that this is a cygwin/bash
problem. Perhaps I am missing something really obvious, I am really a
C/C++ programmer and for the most part am just toying with bash
scripting trying to make an example of a return statement for my
professor who for some reason doesn't know how they work :P. So, any
response would be great.
Thank you.

Here is my bash version:
$ bash --version
GNU bash, version 2.05a.0(3)-release (i686-pc-cygwin)
Copyright 2001 Free Software Foundation, Inc.
Here is my example scipt:
------------start cut------------
#!/bin/sh
mySum()
{
local SUM=0
for i in $*
do
# SUM=`expr $SUM + $i`
done
return $SUM
}
# main body
# call the function
mySum $*
# put the value returned into variable A
# $? contains the return value of the last command executed
A=$?
# print out our variable
echo $A
-------------end cut-------------
