PDOSRT 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).
