AW: Line by Line Relationship in Two Databases

What's a PDB file? Assuming that you meant DBF, and that Data to Display is a One-to-Many relation and that the master record in data has a unique Item per record and that Display carries that Item on all relevant records..

USE Data IN 0 ORDER Date USE Display IN 0 ORDER item

SELECT Display BROWS LAST NOWAIT

SELECT Data SET RELATION TO Item INTO Display BROWS LAST NOWAIT

Now just position both windows side by side, scroll through Data and see Display refresh accordingly.
