Subject: Re: program name -> perl's $0


I don't know of any such list.  The best I can find is this (probably 
incomplete) list from the ruby source:

$$: pid 
$?: last status 
$!: error string 
$/: input record separator 
$\: output record separator 
$;: field separator 
$,: output field separator 
$.: last read line number 
$=: ignorecase 
$:: load path 
$<: reading filename 
$>: default output handle 
$": already loaded files 

Since most, if not all, are copied from Perl, we can probably look at the 
Perl list.
