I have an existing script to automate password resets for a passel o' Cisco switches.   The following snippet is my attempt at having the script prompt for old+new passwords (instead of having them coded in the script's config parameters).

But it doesn't work.  
Looks like keyboard-entered passwords aren't getting pushed(?) into the scalars.   Multiple "uninitialized value" errors result for each of lines 8, 21, 26.

Would any clueful Monks care to enlighten me on whatever fundamental concept/syntax I'm lacking?
    cheers,
