Display of alphanumeric characters and symbols
Alphanumeric characters, numbers, operation commands,
symbols, etc. can be displayed as messages. They must be
within quotation marks.
Messages are also convenient when they display operation
and program results.
Example:
This program calculates the power x of 2. A message of
data entry appears on the screen N=? The result is dis-
played by pressing the button while x is shown on the
screen. When the data introduced is not the power x of
2, the message NO will be displayed and the program will
return to the beginning for you to be able to introduce the
required value correctly.
Assuming that the program is stored in P2: the visualization
is capable of showing up to 12 alphabetic characters simul-
taneously. For messages greater than 12 characters, use
in order to divide the message.
