This entry is used to identify the type of data structure being defined.
If a data structure is not being defined, this entry must be left blank.
- Entry
- Explanation
- Blank
- The data structure being defined is not a program status or data-area
data structure; or a data structure is not being defined on this specification
- S
- Program status data structure. Only one data structure may be designated
as the program status data structure.
- U
- Data-area data structure.
RPG IV retrieves the data area at initialization
and rewrites it at end of program.
- If the DTAARA keyword is specified, the parameter to the DTAARA
keyword is used as the name of the external data area. If the name is a variable,
the value must be set before the program begins. This can be done by:
- Passing the variable as a parameter.
- Explicitly initializing the variable with the INZ keyword.
- Sharing the variable with another module using the IMPORT and EXPORT |keywords,
and ensuring the value is set prior to the call.
- If the DTAARA keyword is not specified, the name in positions 7-21 is
used as the name of the external data area.
- If a name is not specified either by the DTAARA keyword, or by positions
7-21, *LDA (the local data area) is used as the name of the external data
area.
