Description

The ASIZE() function can be used to resize an array. The <array-name> is the name of an existing array to resize. The <expN> is the number of rows the array should be given. For a one-dimensional array the number of rows is the same as the number of elements. If the <expN> is smaller than the original number of rows, the contents of rows higher than <expN> are lost.

Example

declare array1[100]
? alen(array1)
       100
asize(array1,200)
? alen(array1)
       200
 
declare array2[100,5]
? alen(array2)
       500
? alen(array2,1)
       100
asize(array2, alen(array2,1)+1)
? alen(array2)
       505
? alen(array2,1)
       101
