DP4 can automatically generate the programs to export data from and import data to the tables on your DP4 database. This facility assumes that fields are stored in fixed lengths in the file. You can use the facility to transfer information between DP4 databases.
To create an export program, you run the Report Writer automatic generation utility, and enter the name of the table. The generated program will export all the fields on the table to the file named at runtime.
The export program generated in this way is used as a basis for generating the import parameter sets. You run the importer setup utility, and select the export program from the popup list of those on the database. The generated parameters define how a file of data is posted to a table on the database.
