The commands NEW and FREE have been modified to allow string
variables to be defined and released. The syntax for creating
a string variable is enclose the string variable in double
quotes (") when declaring it in the NEW command. String variables
defined this way and used in other commands (including FREE) do
not need the quotes. For example, the following
WIP> new "mystring"
WIP> set mystring some sort of text
WIP> echo "mystring = " mystring
WIP> free mystring
are legal commands.
