SORT-MERGE/XL Files
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.
