Modifying fields in the command-level parameter structure

Some fields that are passed to file control SPI requests are used as input to the
request and some are used as output to the request. The method that your user
exit program uses to modify a field depends on the usage of the field. As a general
rule:

v

On INQUIRE FILE requests, all fields except FILE are output fields.

v

On SET FILE requests, all fields are input fields.

For a full description of the parameters to INQUIRE FILE, see Table 5 on page 92.
For a full description of the parameters to SET FILE, see Table 6 on page 93.
