%lookup on a Data Structure Array

If the customer isn't there, then go to the file and get the value I
need plus add the customer/value to the array.

Generally the "Load as you go" method has always been known to me as
HI-SPEED arrays.
Using HI in the array name helps identify the special use of these
arrays.



I am aware of a potential performance hit of loading the array all at
once.
if you are using an array, and sorting it, is to be sure there is no
"K" on the F-Spec for the file.

This suggestion sounds like the FROMFILE keyword for arrays (load entire
Pre-Run Array from File, using I-specs to select non-contiguous fields)
