User exit 9 is called by ADAULD whenever a compressed record is ready to be written. The user exit decides whether a record is written to DD/OUT1, DD/OUT2, both, or neither.
Notes:
The compressed record pointed to by the third address has the following structure:
AL2 (L1) total length (inclusive) AL2 (L2) record length (inclusive) AL4 (ISN) XL (L2 - 8) '...compressed fields...' XL (L1 - L2 - 2) '...DVT entries...'
The call to the user exit is made via a standard BALR 14,15 assembler instruction. All registers must be saved when control is received and restored immediately prior to returning control to ADAULD. The content of R15 is ignored.
