Assembled here are 120 of the most useful DOS batch files available, written and compiled by Ronny Richardson. Readers gain access to a practical library of programmes designed to boost productivity, enhance DOS performance, and save hundreds of unnecessary keystrokes. Included are batch files for creating and using keyboard macros, saving and reusing command lines, tracking down viruses in COMMAND.COM and more. Richardson not only provides complete batch file code listings, he also offers informative commentary on how and why each programme was written, how it works, and when it should be used. With this valuable collection of batch file tools, DOS users can perform a variety of feats: enter multiple commands on one command line without DOS 5; build help screens into all their batch files; run batch files while storing them in an archive; add password protection; make calculations on the fly using nothing but batch files; modify DOS with DOSKEY; and perform screen magic with ANSI. Richardson also includes several commercial-quality programmes. All programmes in Dr. Batch File's Ultimate Collection - along with Batcmd and BatScreen utilities - come ready to run on an accompanying disk.
