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
