                              MAT ADD. & SUB.


GEN FORM:  MAT ARRAY NAME = ARRAY NAME + ARRAY NAME

                          OR

           MAT ARRAY NAME = ARRAY NAME - ARRAY NAME


MAT ADD ADDS TWO MATRICES WITH THE SAME DIMENSIONS. (EX.  MAT C=A+B).
OR, IN THE CASE OF SUBRACTION, IT SUBTRACTS TWO MATRICES
WITH THE SAME DIMENSIONS. (EX.  MAT C=A-B).
NOTE:  THE SAME ARRAY MAT APPEAR ON BOTH SIDES OF THE EQUAL SIGN

                              MAT ASSIGNMENT STATEMENT


GEN FORM:  MAT ARRAY NAME=ARRAY NAME

THIS STATEMENT IS USED TO SET ONE ARRAY EQUAL TO ANOTHER ARRAY OF THE SAME
DIMENSIONS.  EX.  MAT A=B

ENTER YOUR CHOICE, '0' TO STOP?3


                              MAT....CON STATEMENT


GEN FORM:  MAT ARRAY NAME=CON [NEW DIMENSIONS]

    THE MAT CON STATEMENT SET ALL THE ELEMENTS OF AN ARRAY
EQUAL TO ONE.  (EX.  MAT C=CON(5,10) , MAT D=CON )


ENTER YOUR CHOICE, '0' TO STOP?4


                              MAT...IDN STATEMENT


GEN FORM:  MAT ARRAY NAME=IDN [NEW DIMENSIONS]

    THE MAT...IDN STATEMENT SETS UP AN IDENTITY MATRIX.

                              MAT INPUT STATEMENT


GEN. FORM:  MAT INPUT [ARRAY LIST]

    MAT INPUT ALLOWS YOU TO ENTER ENTIRE ARRAYS FROM THE
TERMINAL.  SINGLE ELEMENTS MAY ALSO BE ENTERED. (EX. MAT INPUT A, OR
MAT INPUT A(4,4))

ENTER YOUR CHOICE, '0' TO STOP?5


                              MAT INPUT STATEMENT


GEN. FORM:  MAT INPUT [ARRAY LIST]

    MAT INPUT ALLOWS YOU TO ENTER ENTIRE ARRAYS FROM THE
TERMINAL.  SINGLE ELEMENTS MAY ALSO BE ENTERED. (EX. MAT INPUT A, OR
MAT INPUT A(4,4))

ENTER YOUR CHOICE, '0' TO STOP?6


                              MAT...INV STATEMENT

GEN. FORM:  MAT ARRAY NAME = INV[ARRAY NAME|

    THIS STATEMENT INVERTS A SPECIFIED ARRAY.  BOTH ARRAYS USED
IN THIS STATEMENT MUST BE SQUARE AND OF THE SAME DIMENSIONS.  THE SAME
ARRAY MAY APPEAR ON BOTH SIDES OF THE EQUATION

ENTER YOUR CHOICE, '0' TO STOP?7


                              MAT MULTIPLICATION STATEMENT

GEN. FORM:  MAT ARRAY NAME = ARRAY NAME 1 * ARRAY NAME 2

    THE MAT MULTIPLICATION STATEMENT SETS A SPECIFIED ARRAY
EQUAL TO THE PRODUCT OF TWO ARRAYS.  THE SAME ARRAY NAME MAY NOT APPEAR
ON BOTH SIDES OF THE EUQUAL SIGN.  THE NUMBER OF COLUMNS IN ARRAY 1 
MUST EQUAL THE NUMBER OF ROWS IN ARRAY 2. 

ENTER YOUR CHOICE, '0' TO STOP?8


                              MAT PRINT STATEMENT

GEN. FORM:  MAT PRINT ARRAY PRINT LIST [PRINT DELIMITER]

    THE MAT PRINT STATEMENT IS USED TO DISPLAY ENTIRE ARRAYS OR 
PORTIONS OF ARRAYS.  WHEN USING THIS STATEMENT, PLACING COMMAS BETWEEN
ARRAYS TO BE PRINTED WILL CAUSE THE ARRAY TO BE SPACED OUT, WHILE ON THE
OTHER HAND IF SEMICOLONS ARE USED THE ARRAY IS PACKED TOGETHER.
(EX. MAT PRINT A,B  , MAT PRINT A;B).

                              MAT PRINT# STATEMENT

GEN. FORM:  MAT PRINT #FILE NUMBER,[RECORD NUMBER];END

                         OR

           
MAT PRINT #FILE NO,[REC. NO.];ARRAY WRITE LIST[PRINT DELIMITER[END]]

    MAT PRINT # STATEMENT IS USED TO PRINT ENTIRE ARRAYS
ON A SPECIFIED FILE. IT IS USED THE SAME WAY THE PRINT# STATEMENT IS.

                              MAT PRINT USIN STATEMENT

GEN. FORM:  MAT PRINT USING FORMAT PART [;ARRAY PRINT LIST]

     THE MAT PRINT USING STATEMENT ALLOWS YOU TO CONTROL THE
OUTPUT OF ARRAYS, OR PORTIONS OF ARRAYS.  IT IS USED JUST LIKE THE 
PRINT USING STATEMENT, UTILIZING AN 'IMAGE'. SEE PRINT USING FOR MORE
INFORMATION.

PRINTED TO ASCII FILES.  IT MAY NOT BE USED WITH BASIC FORMATTED FILES.
