Hi,

I thought I saw a $ variable for the process id on the list a few days ago
but I can’t seem to find it. Could someone please remind me?

Cool! Thanks for the quick response.

An alternative and more readable means of obtaining the PID is:

Process.pid

This brings up the subject of errata for ‘Ruby in a Nutshell’ - p 37,
line 2 reads

$$  The process.pid of the current Ruby Program being executed

instead of

$$  The Process.pid of the current Ruby Program being executed

To John: Please see

2.2 Tell me the posting guidelines for comp.lang.ruby

in the FAQ for this group that is available at

http://rubyhacker.com/clrFAQ.html

If you can read German the pointers in section

2.2.8 Links

of the German version of the FAQ that is available at

http://oss.erdfunkstelle.de/ruby/

Will provide you with additional information about formatting issues
and Outlook/Outlook Express that you might find helpful. Note to
myself: I should look for English language equivalents of the linked
ressources and mail them to Hal.
