Defining Functions › Database Functions › Array Processing

Array Processing

To add, delete, modify, or retrieve entries in a particular array over which they are defined, use the following database functions:

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

A DLTOBJ with no parameters clears an array.

Although arrays are not implemented as database files, CA 2E allows you to use the same techniques as database files when working with arrays.

Note: You must define a key for an array even if the array holds a single element.
