'''COSMOS''' is a personal '''COS'''t '''MO'''nitoring '''S'''ystem programed by [[KSL|KSL]] for the CPC6128 and [[CP/M]]-80 operating system, the latter being the industry standard of the late 70s - early 80s. This budget monitoring system is a business application similar to the MSDOS-era PC applications and one of the most recent (2021) projects developed for CP/M. Unlike most applications for CP/M, COSMOS is built upon the '''mouse based graphics user interface''' as pioneered by Xerox at Palo Alto and popularized by Apple with the Lisa and Macintosh computers. Nowadays, COSMOS can be used on an everyday basis (using [[CaPriCe]] or [[WinCPC]] or a real CPC) in order to edit the daily income, plan the monthly expenses and perform trial and error analyses aiming at maximizing the annual profit. Notice that COSMOS also contains the latest version of [[ASCII Tools]]. <br><br>
