Array Subscripts
Arrays can be declared with default or defined
boundaries known as bounds. Unless specifically defined in the
array declaration statement, default lower bound settings are used.
The default lower bound is zero, unless set by the module
option base statement
setting.
CitectVBA does not have an arbitrary upper bound on array dimensions. The upper bound of the array dimension must be defined before the array can be used. All bound values must be whole integers.
Subscripts are contained within one set of parentheses positioned immediately after the array name in the array declaration statement.
Subscripts are used to specify the bounds of each
dimension of an array when the array is declared. If a single value
is used, for instance (5), this represents the upper bound for that
dimension of the array. If a range is specified, for instance (1
to 9), this specifies both the
lower and upper bounds for that dimension of the array. If more
than one subscript is used, for instance ( 5, 1 To 9), each subscript must be separated by a
comma, and each subscript represents a separate dimension of the
array.
The syntax of an array subscript range consists of a numeric value range separated by the to clause:
(<LowerBound> To <UpperBound>)
where:
(
)are the required parentheses to hold an array subscript
range (dimensions).<LowerBound> represents the lower bound
of the subscript range for the array dimension.To is the clause linking the lower and upper
bounds of the subscript range.<UpperBound> represents the upper bound
of the subscript range for the array dimension.See Also
