Re: Problem using tlookup bif

[Luis Rodriguez <luisro58@xxxxxxxxx>]

As per my (V5R3) ILE RPG  ref. manual:

"Note: Unlike the LOOKUP operation code, %TLOOKUP applies only to tables. To
look up a value in an array, use the %LOOKUP built-in function.

The %TLOOKUPxx builtin functions use a binary search for sequenced tables
(tables that have the ASCEND or DESCEND keyword specified)."
