Hi,

I have changed the old passage:
\textbf{Note.} The target \textit{pgm} depends on the object files \$(OBJ)
and the \textit{Vask Library} \$(VASKLIB). This is done so that 
modifications to any of the \$(OBJ) files or to the \$(VASKLIB) itself will
force module reloading. However, the compile rule specifies \$(OBJ) and
\$(VASK), rather than \$(OBJ) and \$(VASKLIB). This is because \$(VASK)
specifies both the UNIX curses and termcap libraries as well as \$(VASKLIB).


to (new):

\textbf{Note.} The target \textit{pgm} depends on the object files \$(OBJ)
and the \textit{Vask Library} \$(VASKLIB). This is done so that 
modifications to any of the \$(OBJ) files or to the \$(VASKLIB) itself will
force module reloading. Linking against the Vask library is \$(VASKLIB)
\$(CURSES), it specifies both the UNIX curses and termcap/terminfo libraries
as well as \$(VASKLIB).

[sorry for the Latex markup]
Does this change make sense? If not, please correct, then I publish the
updated PDF.

Thanks,

 Markus
