Rob,
I checked perldoc , and it is pretty like reading Latin. I have been
babied by Factor and co. Perl is something else(or should I say
perldoc) , and as if that is not enough Google is not even finding it
easy to search for stuff like $\ and $/. I am not infinitely lazy ,
and naturally I use Google to pick thing out easily. But when Google
is not there to back me up ....I would only depend on your mercy and
stackoverflow.

Yes, $/ is a little more convoluted. Basically it defines how much data
the 'readline' function (same as <>) fetches from the file. By default
it is set to "\n", so that each <FILEHANDLE> will return a string up to
and including the next newline in the file.
Aside from changing it to something special for unusually-formatted
files, these values are possible:
- $/ = undef will read the whole of the rest of the file, with stopping
at any terminators.
- $/ = "" (the null string) will read everything up to one or more blank
lines
- $/ = \999 (reference to any integer) will read (a maximum of) that
much data as the next record, ignoring record boundaries.
HTH,
Rob
