This topic highlights the definitions of the conventions and terminology
used in the DDS information.
- A keyword is a name that identifies a function.
- A parameter is an argument that identifies a value or set of values
you can use to tailor the function the keyword specifies. It is shown between
the parentheses on a keyword.
- A value is an actual value that you can use for a parameter.
- In the keyword descriptions, this field or this record format means
the field or record format that you are defining.
- The expression use this file- or record-level keyword means the
keyword is valid only at the file or record level.
- To specify a keyword means to code the keyword in the DDS for a
file. This contrasts with to select a keyword or when a keyword
is in effect, both of which mean that any conditioning (such as one or
more option indicators) is satisfied when an application program issues an
input or output operation.
- Current source or source you are defining means the DDS
that together make up the description of one file.
- In sample displays, character fields are shown as Xs and numeric fields
are shown as Ns.
- The 5250 Work Station Feature is a feature of the OS/2® communications
manager that allows the personal computer to perform like a 5250 display station
and use functions of the IBM® iSeries™ server.
- Logical file includes join logical files, simple logical files,
and multiple-format logical files.
- Page means to move information up or down on the display. Roll means
the same as page. Paging keys are the same as roll keys. The
PAGEDOWN keyword is the same as the ROLLUP keyword. The PAGEUP keyword is
the same as the ROLLDOWN keyword.
