DDS for display files
Use this record-level keyword to specify that if this record is not already
on the display, it is to be written to the display before an input operation
is sent from the program specifying this record name. If this record is
already on the display, the keyword is ignored. The performance of this
implicit output operation is OS/400-program-initiated; its only purpose
is to format the display when an input operation is performed.
This keyword has no parameters.
This keyword does not apply to output operations.
If the INZRCD keyword is not specified, your program receives an error if
it tries to read a record that is not on the display.
When the INZRCD keyword is processed, the following special conditions
exist:
- For output-only fields, no user data is available. The field
appears on the display as blanks. Any editing specified is
ignored. The BLKFOLD keyword does not affect the display.
- For output/input fields, no user data is available. The field
appears on the display as blanks. The input save area is initialized in
the same way as uninitialized input-only fields (blanks or zeros, depending on
the data type).
- Constants and input-only fields appear the same as when displayed using an
explicit output operation.
- Hidden fields are returned on an input operation as blanks or
zeros.
- Message and program-to-system fields are ignored.
- The LOGOUT keyword is ignored because there is no output buffer to
log.
- The ERRMSG and ERRMSGID keywords are ignored because the record format is
not already on the display.
- The SFLMSG and SFLMSGID keywords are ignored.
- All other optioned keywords and fields are processed as if they were
optioned.
- Note:
- In order for the INZRCD function to be performed, your program must specify a
record format name when issuing an input operation that contains this
keyword. The record format used for the input operation must specify
the INZRCD keyword.
Option indicators are not valid for this keyword.
Example:
The following example shows how to specify the INZRCD keyword.
