RPG/400 Help
- Entry
- Explanation
- PRINTER
- File is a printer file, a file with control characters that can be sent to
a printer.
- DISK
- File is a disk file. This device supports sequential and random
read/write functions. These files can be accessed on a remote system by
Distributed Data Management (DDM).
- WORKSTN
- File is a workstation file. Input/output is through a display
or ICF file.
- SPECIAL
- This is a special file. Input or output is on a device that is
accessed by a user-supplied routine. The name of the routine must be
specified in positions 54 through 59. A parameter list is created for
use with this routine, including an option code parameter and a status code
parameter. The file must be a fixed unblocked format.
- SEQ
- File is a sequentially organized file. The actual device is
specified in a CL command or in the file description, which is accessed by the
file name.
Use positions 40 through 46 to specify the RPG/400 device name to be
associated with the file. On the AS/400 system the file name in
positions 7 through 14, rather than the device name specified in positions 40
through 46, is used to point to the file. The RPG/400 device name
defines the RPG/400 functions that can be done on the associated file.
Certain functions are valid only for a specific RPG/400 device name, such as
the EXFMT operation for WORKSTN. The file name specified in positions 7
through 14 can be overridden at compilation time or run time, allowing you to
change the input/output device used in the program.
Note that the RPG/400 device names are not the same as the system device
names.
