Downloadable and Custom Commands
After defining a download character, we must activate the
download characters in the printer. The code to perform this trick
is:
CHR$(27) CHR$(36) CHR$(1)
let's put all this together in an example and print out a few
of our new paragraph symbols.

Not too bad for the first try. Let's create another symbol to
keep the editors happy and to demonstrate a few more things
you'll need to know about downloadable characters. This time we
will create the copyright symbol; a small c with a circle around it.
First, we'll create the symbol on graph paper and total all the col-
umns as we did for the paragraph symbols.
