Examples
10 DIM A(4),B(4),C(4),D(4),E(2,4),F(2)
20 READ (FOR I=1 TO 4,A(I))
30 READ (FOR I=1 TO 2,(FOR J=1 TO 4,E(I,J)))
40 !
50 ! Form 1:
60 MAT B=A !B has the same elements as A, B(1) = A(1), etc
70 !
80 ! Form 2:
90 MAT C=(2+3) !All elements of C have the value of 5
100 !
110 ! Form 3:
120 MAT D=(2)*B ! All elements of D are worth 2 * B, D(1) =20 ,etc
130 MAT D=B*(2) !Alternate form 3b, results are the same as line 61
140 !
150 ! Form 4:
160 MAT C=A+B !Each element, I of C is the total of A(I) + B(I)
170 !
180 ! Form 5:
190 MAT B=CON ! Each element of B is now 1
200 !
210 ! Form 6:
220 MAT D=SQR(A) ! Each element, I of D is now the square root of A(I)
230 !
240 ! Form 7:
250 MAT C=CSUM(E) ! Each element, I of C is now the sum of the entries
