THE VISIBLE-PASCAL MANUAL
VISIBLE-PASCAL is a special version of Pascal, with the purpose of giving the
first-time Pascal programmer an easy time writing and programming his or her
first programs. Therefore, an easy editor, fast and automatic program
execution and running, and a full symbolic debugger with the program operati-
on and variable values easily visible have been supplied at the expense of
other possible programming features. For example, Visible-Pascal is not a
complete implementation of Pascal; it does not generate programs that run as
fast as possible; and it does not include such advanced features as low level
machine access and modular program construction and linking. It is an
adequate language to allow the writing of interesting and significant
programs, however. Disk files can be read and written; strings are included;
and the various screen modes possible on the IBM-PC can be used, including
the drawing of graphics in
color.
To RUN a program you use the part of the Visible-Pascal system called the
DEBUGGER -- it helps you find and fix program bugs, or errors. The debugger
allows you to watch the operation of the program as it runs, to see whether
it does what you want it to. The debugger allows you to step through a
program, one statement
at a time, while watching the program listing to see what statement is being
executed, and what the values of program variables are. It also allows you to
control how fast the program runs and when it should stop, and allows you to
look at the output of the program (if it writes or draws on the screen) as
well as the information made available by the debugger. Using it is automa-
tic; the Visible-Pascal compiler creates program files which, when 'fed into'
the debugger, automatically make the 'connections' required for all the above
to happen.
Visible Pascal is not Turbo-Pascal compatible. Amongst others the real data
type is missing. No GOTO statement is implied to discourage this use!
