between XFCAREQ and XFCAREQC on a single file control SPI
request.

UEPTSTOK
Address of a 4-byte token which can be used to pass information
between successive file control SPI requests within the same task
(for example, between successive invocations of the XFCAREQC
exit).
UEPRECUR
Address of a halfword recursion counter. The counter is set to zero
when the exit is first invoked and is incremented for each recursive
call.
Return codes
UERCBYP
Bypass this request.
UERCNORM
Continue processing.
UERCPURG
Task purged during XPI call.
XPI commands
All can be used.
API and SPI commands

Note: Take care when using recursive commands. For example, you must avoid
entering a loop when issuing a file control SPI request from the XFCAREQ
exit. Use of the recursion counter UEPRECUR is recommended.
