Description

The ADEL() function deletes the element at position <expN> of the specified <array>. All elements higher than the deleted element will be shifted down and the last element in the <array> will become .F.. The total number of elements in the <array> will remain the same.

For two-dimensional arrays, the <expN> refers to an entire row of elements, rather than an individual element. If the '2' parameter is included, the <expN> refers to an entire column of elements.

Example

element_no = ascan(flist,"New information")
// If element exists
if m.element_no > 0
    adel(flist,m.element_no)
endif
 
//Another Example
set compatible to foxpro
dimension array1(3,3)
array1(1,1) = "one"
array1(1,2) = 1
array1(1,3) = ctod("01/01/2001")
array1(2,1) = "two"
array1(2,2) = 2
array1(2,3) = ctod("02/02/2002")
array1(3,1) = "three"
array1(3,2) = 3
array1(3,3) = ctod("03/03/2003")
//Delete row 2
adel(array1,2)
//Delete column 1
adel(array1,1,2)
