MIDP4PalmOS - My Ruler

MyRuler: MIDlet of a Ruler with inch and Cm marking step

The MIDP application (MIDlet), MyRuler, is my second exercise in MIDP for PalmOS.
Marking of inch and cm will be shown on the screen.
I just checked and aligned on my NR70V. If you can try it on your Palm powered device, please lets me know your result by email me.

It was developed using J2ME Wireless Toolkit. Details of the procedure, refer to the section MyHelloWorld.

Generated PRC file for Palm
MyRuler.prc

Your also need MIDP.prc to run MIDlet on your device.
