- SORT IS PART OF THE KAFS SYSTEM

- KAFS (INCLUDING SORT) IS SHAREWARE AND MUST BE REGISTERED AFTER
- A 30 DAY TRIAL PERIOD.

-
-
- The Record Sorting System (SORT) is an interface program
- designed to sort records that are extracted from data files.
- SORT allows the data file(s) to remain in their original form
- while sorting by 'tags' associated with each record. SORT works
- with fixed length records that are associated with a record
- address. SORT has many advantages over other sorting methods
- such as reduced sorting times, data integrity, multiple file
- data merging and other features.
-
-
-
- Using SORT is very easy. Just include the source code module (or
- related object file) in your compilation and adhere to the
- interface calling conventions described in the SORT Interface
- Specs section. A sample program SORTEST.C is included in both
- source code and its compiled counterpart SORTEST.EXE. Review the
- source code for this sample program and run the program. Doing
- that will present the 'C' programmer with a clearer picture than
- multitudes of description in written form.

- Sort Interface Specs
-
-
-
-
-
- InitSort(int taglength) - Must be called to initialize the
- sort package. An error occurs when there is not enough memory
- available. There must be a minimum of 10,240 bytes available
- for a sort / merge buffer.
-
- RETURNS: OK or SORTERROR
-
-
-
- Sort(char *SortString, long RecordPosition) - Pass the sort tag
- and record pointer to the sort module.
-
- RETURNS: OK or SORTERROR
-
-
-
- Merge(void) - Merges the sortblocks that were written to disk
- (if any).
-
- RETURNS: OK or SORTERROR
-
-
-
- Fetch(void) - Returns the next sorted order tag's record (file)
- position. When the end of sorted records is reached Fetch()
- returns FETCHEND (-1) indicating the end of sorted records.
-
- RETURNS: Records file position (long) or SORTERR or FETCHEND.
- The sort 'TAG' is returned in the 'fetchtag' variable.
-
-
-
- Endsort(void) - Ends a sort process. Releases memory and
- resources.
-
- RETURNS: Nothing
-
-
-
-
-
-
-
- SORT ERROR CODES:
-
- 1 InitSort failed - Not enough memory
- 2 Unable to Open/Create Sort File
- 3 ERROR Writing to Sort File
- 4 Unable to Open/Create Merge File
- 5 Not enough memory for Merge
- 6 Error reading Sort Tag for Merge
- 7 Error Writing to Merge File
- 8 Error Reading Fetch File
- 9 Sort Tag Length Exceeds Maximum
-
-
- SORT Technical Notes
-
-
-
- A SORT 'TAG' is any string that is comprised of any number of
- fields or identifying information about a record or sort element.
-
-
-
- All sort tags must be character strings. Numerics must be
- converted to strings before calling the sort package. All sorts
- are done in ascending order. All returns of SORTERROR are
- further qualified by the global variable 'sorterror'. All
- sorting should follow the order of INITSORT, SORT, MERGE, FETCH,
- ENDSORT.
-
-
-
- SORT is very memory efficient. It can function in as little as
- 10 Kbytes of memory.
-
-
-
- Multiple files can be sorted and fetched by adding the file# to
- the sort tag and using this during fetch.
-
-
-
- When passing the file to generate sort tags select desired
- records and only pass these to the sort.
-
-
-
- SORT uses 2 temporary sort files if sort space requirements
- exceed memory buffers. These temporary files are dynamically
- generated and deleted. All temporary files are released by the
- ENDSORT function. Temporary files are DOS created 'Temp' files
- with a $$$ extension.
-
-
-
- The source code is written for the TURBO C compiler, but can be
- easily converted to other compilers.
-
-
-
- There are 2 global variables of significance to the application:
-
- sorterror - Contains the error code of the last sort error.
-
- fetchtag - contains sort tag of record last fetched.
-
-
-
- SORT is network compatible.
-
-
-
- ** See the SORTEST.C program for examples of SORT usage.
