- LISTSORT.DOC Version 1.0
-
- This program was designed to sort large (500+ listings) RBBS
- directories into alphabetical order for quick reference.
-
- The algorithm is a simple bubble sort except that it only sorts
- the first 12 characters of each line (the filename) in memory to
- allow manipulation of large files. After the array is in
- alphabetical order, every cell of the array is compared to each
- line of the source file to find the original line which is then
- written to the output file.
-
- Unfortunately, with all the disk reads and writes, this program
- is quite slow. I sorted a 1730 file listing which took almost 7
- hours! Reading from and writing to a ramdisk speeds up the
- process considerably. The best time to run it is while you're
- asleep.
-
- The upper limit for directory size is about 2500 files. To go
- beyond this you would have to change the source code to read
- fewer characters into the array.
-
- To run the compiled program, type LISTSORT. You will then be
- asked for input and output drives (where necessary) and
- filenames. Be sure to allow approximately as much free file
- space as the input file on your output disk.
-
- I hope you find this program useful.
