DIMENSION Statement (DataBasic) (m618703+dimension_s.htm)
Dimensions arrays so they can be used in a DataBasic program.
DIM{ENSION} arrayName(dimensions){,arrayName(dimensions)...}
arrayName The name of the array to be dimensioned.
dimensions The size of the array.
An array can be one-dimensional, (vector) or two-dimensional (matrix). See Dimensioned Arrays for more details and the limits on the number of elements.
The maximum dimensions of an array must be specified with a DIMENSION or COMMON statement. The dimensions must be declared with literal integers greater than 0 or symbols that represent literal integers, separated by commas. A DIMENSION (or COMMON) statement must precede any reference to the array it dimensions and is usually placed at the beginning of the program.
An array that is specified in a COMMON statement must not be specified in a DIMENSION statement.
You can dimension several arrays with a single DIMENSION statement. For example:
DIMENSION A1(10, 5), X(50)
This example declares Array A1 as a 10 by 5 matrix and declares Array X as a 50-element vector.
Notes:
DIMENSION MATRIX(10, 12)
Specifies a 10 by 12 matrix called MATRIX.
EQU ROWS TO 10
EQU COLS TO 12
.

.
DIMENSION MATRIX(ROWS, COLS)
Specifies the same matrix as above, using symbols for the dimensions.
DIM Q(10), R(10), S(10)
Specifies 3 vectors named Q, R and S, each of which contains 10 elements.
