{\bf \large Abstract}
\end{center}
The pic language is the language of a batch-oriented troff
preprocessor, called pic, for specifying line drawings in UNIX
environments.  In this work, a convenient graphical interface, a
WYSIWYG, direct manipulation editor for pic users, was developed in the
X Windows environment, using Motif. WD-pic combines graphics and text
building and picture editing and produces pictures on the screen and a
corresponding internal representation, which is fully compatible with
the pic language.

WD-pic was constructed using some newly developed code, the Motif
library, and code from the original batch-oriented pic compiler.
Specifically, the original pic compiler's source code was modified and
incorporated as a separate process in WD-pic. WD-pic was tested by the
author and showed a number of advantages and disadvantages over the
batch pic program.
