 This is an unsorted archive of (VMS-)programs collected over years 
 mainly from comp.os.vms postings and Decus.de notes discussions.
 It is by no means a legal and up-to-date mirror of freeware archives elsewhere.
 Please first look into the usual archives before getting a software from here.
 Some of the sources have been edited and readied to compile,
 some are just as saved from the newsreader. 
 If not otherwise stated in individual files, programs are assumed to be covered 
 by the GNU general public license, which can be read in file gpl.txt .
 Filenames in packages are those after unpacking on a VMS ODS2 volume, 
 i.e. case is not preserved, and they are not suitable for non-VMS systems.

A note to users of MS InternetExploder:
All source files here are sent using mime-type text/plain in the HTTP response header.
MSIE is apparently ignoring the HTTP header, and misusing the filename extensions like .FOR,MAR,.C,.H to decide how to display the file in the browser, resulting in strange line-breaks.
Those files can either be downloaded by using the menu File->Save target as... on the link, or using View->source in the browser.
