Subject: I'm confused about $LOAD_PATH



Hi,
I'm confused about how to update this $: variable in a ruby program.

In the Ruby book PPG  (page 218 in my book) it says that this variable
is read-only , but in the same sentence,
it says
"This variable can be set from within a program to alter the
default search path; typically programs use $: << dir
to append dir to the path. [r/o]"

The book says in several places that you can update
this variable at runtime, BUT, when I try
     $LOAD_PATH = $LOAD_PATH << "mydir"
 or
     $LOAD_PATH = $LOAD_PATH.unshift "mydir"
I get,
     "$LOAD_PATH is a read-only variable (NameError)"

Regards,
Tad
