Visible-PASCAL, A PASCAL compiler, is particularly useful for teaching
and learning PASCAL.  With this package, users can watch the operation
of a program as it runs.  There are 19 different sample programs which
can be edited or run.

AUTOEXEC BAT  Starts program from boot disk.
EDIT     BAT  Batch file to start the editor
ERR      TXT  Text file containing error messages
G        BAT  Batch file that explains how to start the program
MANUAL   1    User manual part 1 of 2 (27K)
MANUAL   2    User manual part 2 of 2 (52K)
PRINTMAN BAT  Batch file that prints the manual
RUN      BAT  Batch file to run a program
