PUA For DOS is a set of batch files designed to enhance the life of any
 computer user.  Power Users' Aliases for DOS, as the name implies, are
small utilities which do nothing but save your valuable time.  Best of
all, all of the utilities here are completely public domain, which not
only means that you are free to use and modify all of them as you wish,
but you can use them in any of your applications since there is no
copyright held on any of the batch (.BAT) or BASIC (.BAS) files.  The
.COM files may be distributed for noncommercial use free but may not be
sold or used in commercial applications.  The following gives you a brief
idea of some of what you can look foreward to in this set:
4D, for example, checks if 4DOS (a COMMAND.COM replacement) is loaded.
A very common complaint amongst computer users is that they have no way
of knowing whether they can use the specialized batch language of 4DOS.
This program sets an environment variable to 1 if 4DOS is loaded.
ANSIDET detects if an ANSI driver is installed.  Another common problem
I have been noticing lately is the lack of any certain ability to find
out easily if an ANSI capable driver is available.  The most common
technique is to find "ANSI" in memory, but what if the driver uses a
different name?  This program uses the same method as many BBS programs.
It sends a special code to the screen, which is interpreted and
responded to by the ANSI driver if one exists.
DT is a replacement for both the DATE and TIME commands.  It displays
both the date and time in a more friendly format, and does not prompt
for new settings unless the /S command is used.

Entire package is either public domain or freely distributable.  No
compensation of any sort is required.
