# User Exit 3 (User-Defined Phonetic Processing)

This user exit may be used to perform user-defined phonetic processing. It is given control by the ADACMP utility or the Adabas nucleus whenever phonetic processing is required.

The user exit must develop a three-byte phonetic key using the value supplied. The address of the resulting phonetic key must be placed at 8(R1) before control is returned.

## Input Parameters

Register 1 contains the address of the following parameter list:

##### User-Defined Phonetization User Exit (3) Parameters

Parameter | A fullword address of . . .
--- | ---
0(R1) | the four-byte length for the value to be phonetically processed.
4(R1) | the address of the value to be phonetically processed.
8(R1) | a three-byte location to contain the phonetic key. This address is set to zero before the user exit and must be set to the actual address during the user exit.

The call to the user exit is made using a standard BASR 14,15 assembler instruction. All registers must be saved when control is received and restored immediately prior to returning control to Adabas. The content of R15 is ignored.
