Example
N20 G00 Z0.0
N22 G01 Z–12.00 F.015
When block N22 is first read by the control, the value Z–12.000 will appear under the DISTANCE TO GO readout in the upper right corner of the screen. After moving a distance of 1 inch, the value of coordinate Z changes to Z–11.000, and so on. The other displays, ABSOLUTE and RELATIVE, correspond to the first two display screens, but this time they are smaller so that all four displays may fit on one screen. All of the displays may be changed to read in millimeters, with respect to Machine Zero, by changing a machine parameter or by using a G-Code in the program.
The codes listed in the lower left corner of the display pictured in Figures 2-24 and 2-25 are the default G-Codes that are active upon startup of the machine. They are also reinstated by pressing the RESET key.

MDI OPERATIONS
You may input small programs via the keypad at the control. The size of the program, which is limited to 10 lines on the control described in this book, is determined by the parameter setting from the manufacturer. Small programs provide an excellent method of executing simple commands like tool changes, controlling the spindle r/min and its rotation direction, etc. To enter the MDI mode of operations, follow these steps:
1. Press the MDI button on the Operator Panel.
2. Press the PROGRAM function key.
3. Enter the data to be executed by using the methods described later in the section Program Editing Functions.
For the program number, the control assumes O0000 and the data may be entered. Each block ends with the end-of-block (EOB) character (;) so that individual blocks of information can be kept separately. For example:
N1
