[Linux] Re: PERL SCRIPT WRITING

[Jonathan Gathman]

Hi Ronda!
   Regarding home movement:

   Elizabeth is coming July 7 to help finish up with getting this house 
ready to sell.  We're excited that she is coming!  Right now, we are 
pre-packing (i.e. decluttering) is part of that process, along with a 
thousand other details.  The closing date on the new house is Aug 20, wo 
regardless of what happens on this house, that is when we'll start 
moving to the new one.

   Regarding Perl:
   If you have Linux, it's usually part of the installation, or you get 
it off the disks.  Stuart usually recommends "freshmeat.net".  However, 
there is also a "Perl.com", run by O'Reilly, the computer publisher. 
That appears to be a center for downloading, so I'm sure it has Windoze 
versions...

   One of my coworkers recently taught a Perl class for our extended 
group.  I will ask which book he used, but I suspect it was O'Reilly. 
I'll write back when I hear from him.

Take care,

Thanks for writing!
