- PDSORT 2.1.2 (June 20, 1990) removed the special quicksort routine -
- the standarg qsort() routine supplied with Turbo C++ 1.0 is faster
- than the special!
-
- PDSORT 2.1.1 (June 17, 1990) fixed a small problem in the quicksort
- routine that caused excessive sort times on a few files. This version
- was also recompiled with Turbo C++ 1.0.
-
- PDSORT 2.1.0 (June 5, 1990) is the second public release of PDSORT.
- This release fixes a problem with the default key (the entire record)
- that caused a Stack Overflow. It also uses a replacement for the
- standard qsort() that is several times faster, particularly on files
- that are in near order. The error checking has also been increased.
- There are no functional enhancements in this version, however.
-
- PDSORT 2.0.0 is the first public release of PDSORT, all of the
- versions 1.x.x had errors far to major to allow release. PDSORT is
- not the fastest of the sorts, QUIKSORT, the fastest that I have found
- so far, is three times faster. PDSORT is, however, free and fully
- public domain. The ZIP file contains all of the C source for the
- program (Turbo C 2.0 compatible).
