IntroductionDROS is a DOS like shell written in MIDP with a BASIC interpreter for the writing of simple programs. This brief user guide is split into two parts a user guide for the DROS environment and a guide to the BASIC interpreters API.

Because the application requires access to the file system the application requires JSR 75 file system support on the phone. Phones that have this present (at thetime of writing the document) are Sony Ericsson phones starting with the K750i. Nokia Series 60 (Symbian) phones starting with the 6630. Nokia Series 40 phones starting with the 6230i. Siemens phones starting with the 75 Series. It should be noted that some network operators such as Cingular and T-Mobile in America disable the JSR-75 file support so the application will not work.

By pressing the * button a scrolling mode is entered where by using the up and down direction keys the session so far can be viewed. Pressing * again returns to the normal command input mode.
