Program Title:  Doug's Programming Language (DPL) version 2.22
PC-SIG version: 1

DPL, or Doug's Programming Language, is a macro language which uses high
level language syntax for its instructions.

DPL's language does not limit the programmer from using native 8088
code, but makes programming easier by automatically declaring segments
and the program entrypoint.  All return codes except end-of-file are
standard DOS return codes.  The program handles 64K of code and data and
stack segments.  Variables are automatically declared.

DPL supports simple data types and still permits the programmer to build
other types.  Basic data types supported are 16 bit integers and ASCIIZ
strings.  The 16 bit integers are considered to be signed integers and
therefore will be manipulated appropriately.  Files are supported which
allow the program to address any disk file or logical device, such as
the keyboard and screen.

Extensive documentation is available on disk in both standard ASCII and
WordStar format.  Also available is the DPL source program written in
TURBO C.  A large number of application routines and application routine
construction files are provided, along with a demonstration of the use
of shade and how to manipulate it.
