WCD - Wherever Change Directory

Wcd is a command-line program to change directory fast. It saves time typing at the keyboard. One needs to type only a part of a directory name and wcd will jump to it. Wcd has a fast selection method in case of multiple matches and allows aliasing and banning of directories. Wcd also includes a full screen interactive directory tree browser with speed search.

Verjrdag is een eenvoudige verjaardagkalender voor DOS, Windows en Unix. Verjrdag waarschuwt vooraf en achteraf. Het aantal dagen vooraf en achteraf is in te stellen.

DosDir 2.1a

Download here the latest version of DOSDIR. DOSDIR is freeware. Partly under the GNU General Public Licence conditions.
It uses the DOS directory framework to provide a portable interface for MS-DOS/UNIX/VMS application programmers. DOSDIR minimizes the OS- specific directory access code for applications allowing programmers to concentrate on the application itself and not on the low-level directory and file structure. DOSDIR applications will run on their native operating systems with the appropriate file syntax and handling, which is expected for that platform.

DosDir is written by Jason Mathews. View the README.

Man 1.3

A 16 bit DOS port of Eli Zaretskii's man clone for DJGPP v2.

This is a simple `man' clone. It can be used to display Unix man pages, both formatted and unformatted. It can also be used to display pure-text docs, provided that the directory where these files are kept is mentioned in the MANPATH environment variable; this makes it especially suited to the PC environment where typically each program or package come with some kind of text-only documentation.

A 16 bit 'groff' is currently missing, so unformatted man pages cannot be viewed yet.

View the README and ChangeLog.
