A database issued as part of a system built with DP4 is normally distributed to users on the CD ROM used to install the application, or alternatively as a backup file spread over several disks. A database distributed in this way includes any Report Writer and QA Build programs you have created. In the latter case the database is restored at the user site by running the utility to restore a database.
If any executable programs associated with the system use an operating system different from your development system, you need to convert the programs before they are distributed.On 16 bit systems, provided that you follow the guidelines for producing operating system-independent programs, no re-compilation is necessary. In 32 bit environments recompilation is required, but it normally straight forward, provided you use only the DP4 APIs or ANSI APIs for C/C++.
