Portfolio Tone Generator  -  V01.00

                          by Carl Koop



     PORTTONE.COM, the Portfolio Tone Generator, is a simple 
program designed to allow you to make use of the Portfolio's 
built in melody tone generator.  PORTTONE requires no additional 
files (such as ANSI.SYS or BEEP.COM) to execute and will accept 
input either directly from the keyboard or from a text file. 

     PORTTONE will translate the alphabetic characters A through 
Y to the 25 different tones that the Portfolio is capable of 
generating.  When the letter Z is detected PORTTONE will go to 
end of task.  Input can be either upper or lower case and any 
characters other than A through Z will be ignored by PORTTONE.

     In order to use a text file for input PORTTONE uses 'C's 
standard input redirection character (<)followed by the name of 
the file.  For example to run PORTTONE with the file MUSIC.TXT 
used for input the command would be: PORTTONE <MUSIC.TXT

     NOTE: When using a file for input please be sure that the 
last character in the file is the letter Z.  If the Z, which 
tells PORTTONE to terminate, is omitted PORTTONE will fail to end 
when the end of file is reached and you will need to re-boot your 
Portfolio.


     The following is a list of the characters acknowledged by 
PORTTONE and the notes that they correspond, or translate, to :


     A - D#5             B - E5              C - F5
     D - F#5             E - G5              F - G#5
     G - A5              H - A#5             I - B5
     J - C6              K - C#6             L - D6
     L - D#6             M - E6              N - F6
     P - F#6             Q - G6              R - G#6
     S - A6              T - A#6             U - B6
     V - C7              W - C#7             X - D7
     Y - D#7             Z - EXIT



     I hope that you find PORTTONE a fun diversion from your 
normal use of the Portfolio, but please remember that tone 
generation on the Portfolio will put significant wear on your 
batteries.
