DIM<n>(array-name) |
DIM(array-name,bound-n) |
Details |
The DIM function returns the number of elements in a one-dimensional array or the number of elements in a specified dimension of a multidimensional array when the lower bound of the dimension is 1. Use DIM in array processing to avoid changing the upper bound of an iterative DO group each time you change the number of array elements.
Comparisons |
Note: This distinction is important
when the lower bound of an array dimension has a value other than 1 and the
upper bound has a value other than the total number of elements in the array
dimension.
Examples |
In this example, DIM returns a value of 5. Therefore, SAS repeats the statements in the DO loop five times.
array big{5} weight sex height state city; do i=1 to dim(big); more SAS statements; end;
This example shows two ways of specifying the DIM function for multidimensional arrays. Both methods return the same value for DIM, as shown in the table that follows the SAS code example.
array mult{5,10,2} mult1-mult100;
Syntax | Alternative Syntax | Value |
---|---|---|
DIM(MULT) | DIM(MULT,1) | 5 |
DIM2(MULT) | DIM(MULT,2) | 10 |
DIM3(MULT) | DIM(MULT,3) | 2 |
