AFTER YOU HAVE RUN A PROGRAM, JUST

"EXEC DISP VAR".  IT WILL GIVE YOU A

LIST OF ALL THE VARIABLES USED SO FAR

IN YOUR PROGRAM.

   IT USUALLY ADDS ONE VARIABLE TO THE

LIST.  THAT IS "AV" WHICH WILL BE THE

LAST VARIABLE LISTED IF "DISP VAR"

ADDED IT.  "AV" IS THE POINTER TO THE

BEGINNING OF THE ARRAY VARIABLES.

IF "AV" IS ANYWHERE BUT LAST IN THE

THE LIST, THEN IT WAS A VARIABLE OF THE

PROGRAM.


   OR, YOU MAY WANT TO KNOW WHAT VALUES

EACH OF THE VARIABLES CONTAINS.  IN

THAT CASE, "EXEC DISP VAR VALUES".  THE

SCREEN WILL CLEAR, AND A PRINT STATE-

MENT WILL APPEAR AT THE TOP: SOMETHING

LIKE--

]?R$,M,EA,F%,Q$,M$,B,AV,

   USE THE RIGHT ARROW KEY TO TYPE OVER

THE ENTIRE STATEMENT AND PRESS RETURN.

A TABLE OF ALL THE VARIABLE'S VALUES

WILL BE DISPLAYED.  THESE VARIABLES:

AV, SV, I, AND A$, MAY HAVE THE
--  --  -      --
WRONG VALUES, BECAUSE "DISP VAR VALUES"

USED THEM TO FIND THE OTHER VARIABLES.

   THIS ROUTINE IS GREAT AS IT STANDS,

BUT WOULDN'T IT BE SLICK IF IT DIDN'T

ADD "AV", OR IF THE VARIABLE VALUES

WERE PRINTED IN TABULAR FORM WITH THE

VARIABLE NAMES?   SOMETHING LIKE:

 A$ = "SINE"          B   = 5.3092
 F% = 109             NO$ = "NO!"


MAYBE A ROUTINE WRITTEN IN MACHINE

LANGUAGE COULD DO ALL THAT...

ANYONE OUT THERE WANT TO TRY?
