CURSOR.TPU
Cursor Control Turbo Pascal Unit
by David C. Swaim II
There are times, like when you are setting up a highlight bar
menu, that you do not want to have a flashing cursor on the screen.
Turbo Pascal has no built in procedure to turn off and on the cursor so
without some external procedure you cannot cut off the cursor. That is
what these procedures are designed to do.
The CURSOR.TPU unit is a very small and simple Turbo Pascal unit
which has only two procedures which have two very specific functions.
The CursorOn procedure will turn the blinking cursor on and the
CursorOff procedure will turn off the cursor so it is not visible. To
turn off the cursor in a Turbo Pascal program simply put:
CursorOff;
in your program at the appropriate place. To turn the cursor back on
put:
CursorOn;
in your program. The CursorOn procedure gives a large block cursor
instead of the underline cursor that is normal for DOS. I have found
that many people have trouble finding the cursor on a busy input screen
on monochrome monitors or on laptop displays. Therefore all my
programs use a block cursor.
Note: The cursor procedures in the CURSOR.TPU are also included in the
INPUT.TPU unit so if your program uses INPUT you already have access to
the cursor procedures without listing CURSOR in your uses clause.
