C  THIS PROGRAM CREATES FUNCTIONS FOR THE MUSIC PROGRAM USING 
C  'SEG' OR 'SYNTH'.  UP TO 10 FUNCTIONS CAN BE STORED IN A
C  SINGLE FILE.  ONCE CREATED, THE FUNCTIONS MAY BE CHANGED
C  AND PUT BACK IN THE SAME FILE OR INTO A NEW ONE.
C  NO MORE THAN 50 INPUTS FOR ONE FUNCTION!
C TYPE 'C'(= CRUNCH)  FOR SPECIAL FEATURE SUBR TO COMBINE FUNCS 
C ALREADY MADE.      [MULT, ADD, RETRO, INVRT, ADD CONSTANT ]

C  SEG FUNCS MAY BE 'SMOOTHED' BUT THIS FEATURE AND 'CRUNCH' SHOULD 
C  BE USED SPARINGLY AS ALL 512 WDS OF THE ARRAY MUST BE SAVED.  THIS
C  CLUTTERS UP THE DSK.

C  'C' FOR "ALTER OR FINISH?" WILL JUMP DIRECTLY TO "CRUNCH" MODE.
C    BUT ONCE CHANGED BY 'CRUNCH' THIS UNSTORED ORIG. IS LOST.
C  'SP' (FOR "SEE") WILL PLOT ONE AT A TIME.
C  'SA' PLOTS ALL IN .FUN FILE ON CALCOMP
C  'SX' PLOTS ALL IN XGP FORMAT. (1ST→ <CTRL C>, A DSK PTP  --
C -- WHEN DONE→ <CTRL C>, F )  THEN USE "X" PROG. TYPE 6,11,1.

C FOR EXPONENTIALS GET INTO 'SEG'.  TYPE 'X', DECAY FAC, N.  IF 
C  N IS NON-ZERO THE FUNCTION WILL NOT! NORMALIZE (IE. NOT GO TO 0).
C  THE DECAY FAC. IS THE NUM ALONGTHE SCALE(1-100) WHERE THE CURVE
C  SEEMS TO TOUCH ZERO. (WILL ALWAYS HIT 0 AT END UNLESS N.NE.0.)

C AFTER FILE IS READ IN, <CR> FOR 'TYPE FILE' WILL HOLD ON TO IT.
