Starting in 4D 2004, you can append an element to an array with only one line of code. A new command called APPEND TO ARRAY has been added to ease the process and reduce the amount of code that you have to write.

INSERT ELEMENT($myarray;Size of array($myarray)+1)
$myarray{Size of array($myarray)}:=$myvalue

can now be replaced with:

APPEND TO ARRAY($myarray;$myvalue)
