- This text describes the use and operation of the Universal Globals System
- Utilities which enhance PC-DOS 2.xx to take full advantage of multiple
- directories and devices. The user is able to invisibly access files outside
- the current default directory. Applications programs can then run from any
- directory on the system without modification.Path names are not required for
- the master programs to find their supporting files once the Universal Globals
- have been set in operation.
-
- PC-DOS 2.xx provides a tree structured file system which permits effective
- organization of data and programs in the file system. However problems arise
- with multiple directories since each new directory must contain data on where
- certain programs and files are located or contain the files themselves. With
- DOS 2.xx the user may tell the operating system to look for programs in a
- specified path of directories or devices. This is the program search path set
- by using the DOS path comand.
-
- PATH =F:\;B\SUBDIR\SUBSUB
-
- However any files used by the main operation progams such as overlays,or
- support files are looked for on the current directory unless a full pathname
- is provided.The output files are also created in the default directory.
- The Universal Global System eliminates this problem by creating the idea of
- a global system.
-
- 1) A single filename may be explicitly applied to a full path name and then
- every occurrence of the filename will be replaced by the the corresponding
- path name.
-
- 2) A set of filenames may be grouped by either a filename or extension and
- thus may be implicitly applied and set to a common directory.
-
- For both forms of application search rules are permitted for which a list of
- filenames or directories are searched until an appropriate match occurs.
- Wildcards of * and ? extend the search.
-
- Thus disk usage is much more efficient since only a single copy of the
- program need be kept in the system. New directories and disks can be used
- immediately without having to copy any files onto them and the full potential
- of the ram disk is now much improved.
-
- Universal Global System also provides a convienent way of accessing files in
- widely separated areas of the file system, in a way similar to the Berkeley
- Unix Shell but yet not the same.

- There are several other useful commands available on the disk if you registerThis text describes the use and operation of the Universal Globals System
