item list
Prints an item
or a list of items on the Display. The items
may be either string
constants
(messages enclosed in quotes), string variables, numeric
constants
(numbers), variables, or expressions involving all of the
preceding items. The
items
to be PRINTed
may be separated by commas or semi-colons. If commas
are
used, the cursor
automatically advances to the next print zone before
printing the
next item.
If semi-colons are used, no space is inserted between the items
printed on
the Display.
In cases where no ambiguity would result, all
punctuation can be
omitted.
