Database Functions

Database functions specify basic routines for updating the database. There are four different database functions, each defining a subroutine to either create, change, delete, or retrieve data. Database functions are implemented as part of an external standard function. All database functions are internal functions. Once you define a database function you can use it in many different functions.

The database functions are:

• Create Object (CRTOBJ)
• Change Object (CHGOBJ)
• Delete Object (DLTOBJ)
• Retrieve Object (RTVOBJ)
