This module contains the user exit code; each of the following entry
points is called from IBMSPL with T1 containing the address of the beginning
of an ASCII record, and T2 containing the number of ASCII bytes. The user
exit can only modify register T2 (the most useful being to set it to 0 to
delete the record), and should be careful not to wipe out other memory.
The user exit can also modify the record, but it must do so in place (i.e.
it cannot change T1 to point to a new buffer).
