SORT-MERGE/XL uses several different types of files during
its operation. These file types are defined below:
Display File |
 |
The display file receives the output from the >SHOW command. This output can be in the form of either
the translation table or the collating sequence. The formal designator
of the display file is DISPLOUT, which defaults to $STDLIST. $STDLIST is the terminal for a session and the printer
for a job.
Input File |
 |
The input file contains the data you want to sort or merge.
This file can reside on any storage device such as magnetic tape
or disc. For SORT-MERGE/XL, the formal designator of the input file
is INPUT. INPUT is then equated to the actual file designator
you specify with the >INPUT command. $NULL is not a valid input file.
Output File |
 |
The output file receives the results of the sorted or merged
records. The formal designator for the output file is OUTPUT which is equated to the actual file designator
you specify with the >OUTPUT command.
List File |
 |
The list file is used by SORT-MERGE/XL to display error messages
and prompts during interactive sessions. It does not contain sorted
or merged records. The formal designator for the list file is LIST, which defaults to $STDLIST. $STDLIST is the terminal for a session and the printer
for a job.
Scratch File |
 |
The scratch file is used as a work area by SORT/XL. It is
not used by MERGE/XL. The formal designator for the file is SORTSCR in Compatibility Mode. In Native Mode, there is an
unnamed scratch file. Refer to the discussion of the >INPUT command for SORT/XL to estimate the size of the
scratch file. All extents for the file are allocated at once.
Text File |
 |
SORT-MERGE/XL reads commands directly from this file. The
formal designator for the file is TEXT, which defaults to $STDIN.
Prompt File |
 |
Used by SORT-MERGE/XL to prompt the user for input when the
text file is the session terminal but the list file is not. PROMPT is the formal designator which defaults to $STDLIST. The prompt file is the session output device.
