NDIM%

Syntax NDIM% (array)
Location NDIM

This function returns the number of dimensions of a given array. DIMmed variables of any type (floating point, integer and string) are legal parameters.

Example

DIM test% (10,50,2)
PRINT NDIM% (test%)

gives the answer 3.

NOTE

String arrays often have one more dimension than the number of elements which they can hold. This extra dimension sets the maximum length of each element, for example:

DIM name$(100,20)

sets aside space in the array name$ for 100 strings, each of which can be a maximum of 20 characters long:

PRINT NDIM%(name$) returns 2.

CROSS-REFERENCE

DIMN finds the defined size of each dimension and can be used to replace NDIM%. DIM declares an array. NDIM is exactly the same as NDIM%.
