RexxBase is a freeware DLL with a REXX interface allows you to access dBase III and IV files, it supports for DBF, DBT, NDX and MDX files and comes with an executable program that provides simple front-end to database development.

RexxBase generates dBase field names and values that are available directly to a Rexx program. The Rexx program can change this data and update dBase files directly. Also database file control information is available to Rexx procedures. This information includes such data as last date the database was updated, number of records on file, field names, etc.
