# Functional Overview

Note
All ADADBS functions can also be performed using Adabas Online System (AOS). When using the Adabas Recovery Aid, using AOS is preferable for file change operations because it writes checkpoints that are necessary for recovery operation.

Any number of functions may be performed during a single execution of ADADBS.

## Syntax Checking with the TEST Parameter

The ADADBS functions now include a syntax-checking-only mode. When the TEST parameter is specified, the ADADBS function syntax is checked, but not performed.

The ADADBS utility can perform multiple functions. As a result, ADADBS reads the parameters up to the next specified ADADBS function, and then executes the function/parameters just read. Then, ADADBS reads the function and parameters up to the following function, and so on. Therefore, to ensure that no functions are executed, the TEST parameter must be specified either before or within the first function/parameter group, as the following example shows:

    ADADBS TEST
    ADADBS DELETE FILE=1
    ADADBS DELETE FILE=2
