How can I make a box, or window... which will be control the motion of
 the motors which are connected for the parallel port, I mean, in that box or window
I will send the information to move the motors as the number of steps I want to move
them,or the number of degrees that the motors move.....

The simplest way to that is :

1 - Add two buttons to your form as Button1and Button2
2 - Button1.Caption := 'Step By', Button2.Caption := 'Step Degrees'
3 - On Button1Click
     StepBy := StrToInt(InputBox('Enter steps to move the motor','','2'));
4 - On Button2Click
     StepBy := StrToInt(InputBox('Enter degrees to move the motor','','30'));

More user friendly way is to use TTrackBar component in Win95(or Win32 tab if you use Delphi 3.0+):
1 - Just place 2 tractbar components to your form. One for steping by steps and other for steping by Degrees(or radians)
2 - OR place two SpinEdit controls to do the same

Hi
Thanx for the help, I think that the Ttrackbar is a  good solution, but I don't know to
put them in the form, the procedure which I need, etc... if one of them is for the
stepping by degrees, how can i do that, in the trackbar i define the number of degrees, e.g.  from 0 to 360 in intervals of five degrees and how can I send this information to the
motor which is connected in the parallel port for the pin D0 and D1..., the pin D0 is for the
direction of the motor (clockwise and ccw) and the D1 is for the clock of the motor..
If you have any advice to this, please help me
Many thanks
Guerra
