Variable Types
ARRAY VARIABLES
An array is a group or table of values
referenced by the same variable name. Each
element in an array is referenced by an array
variable that is subscripted with an integer or
an integer expression. An array variable name
has as many subscripts as there are
dimensions in the array. For example V(lO)
would reference a value in a one-dimension
array, T(l,4) would reference a value in a two-
dimension array, and so on. The maximum
number of dimensions for an array is 255. The
maximum number of elements per dimension
is 32,767. Both these values are also limited by
the memory size of your system.
Wherever a variable name can be entered in a
GWBASIC program line, an array element
can also be entered. From now on, when
speaking of a variable we shall mean either a
simple variable or an array element.
