Short testcase:

Code:
$ cat foo
#!/usr/bin/bash

function foo {
    echo -n hi

    # Uncomment this line to change the output from "hi again hi " to "again ".
    exit 0
}
foo
echo again
foo
$
$ foo
hi$
$

OK, I have a working version now. It's not very polished but hey -- it's my first script! It took me about three hours, but there was a lot of reading in that time.

I'll chalk that up to 'bizarre things happen some times' or something. Smilie
