To eliminate arrays from a program.
ERASE list of array variables
Arrays may be re-dimensioned after they are erased, or the memory space previously allocated to the array may be used for other purposes.
If an attempt is made to re-dimension an array without first erasing it, an error occurs.
200 DIM B (250) . . . 450 ERASE A, B 460 DIM B(3, 4)
Arrays A and B are eliminated from the program. The B array is re-dimensioned to a 3-column by 4-row array (12 elements), all of which are set to a zero value.
