The routine returns the lower and upper pixel-index bounds of each dimension of an array, together with the total number of dimensions.

CALL ARY_BOUND( IARY, NDIMX, LBND, UBND, NDIM, STATUS )

IARY = INTEGER (Given)

NDIMX = INTEGER (Given)

LBND( NDIMX ) = INTEGER (Returned)

UBND( NDIMX ) = INTEGER (Returned)

NDIM = INTEGER (Returned)

STATUS = INTEGER (Given and Returned)

• If the array has fewer than NDIMX dimensions, then any remaining elements of the LBND and UBND arguments will be filled with 1’s.

• If the array has more than NDIMX dimensions, then the NDIM argument will return the actual number of dimensions. In this case only the first NDIMX sets of bounds will be returned, and an error will result if the size of any of the remaining dimensions exceeds 1.

• The symbolic constant ARY__MXDIM may be used to declare the size of the LBND and UBND arguments so that they will be able to hold the maximum number of array bounds that this routine can return. This constant is defined in the include file ARY_PAR.
