Chapter 4 Using the Database After you design the database, create the root file, and build the data sets, you can write application programs to enter and use the data. Programs written in BBASIC, C, COBOL II, FORTRAN 77, or Pascal gain access to the database through calls to TurboIMAGE/XL procedures. RPG programs contain specifications used by the Report Program Generator to make calls to the TurboIMAGE/XL procedures for you. This chapter contains a text discussion of the procedures used to open the database and to enter, read, update, and delete data; it also contains information on locking, transaction logging, checking procedure status, and interpreting errors. Use this chapter with chapter 5 which gives details about each procedure call, its parameters, and status information.
NOTE Before application programs can be executed, the database must be created using the TurboIMAGE/XL utility program DBUTIL described in chapter 8.
