Abstract
A personal computer has been used to save labour and time in handling the data of patients with colo-rectal cancer. The program was written in N-88 BASIC to run on PC-8800 series equipment (PC-8801 processor, PC-8881 floppy disk unit, PC-8822 printer and PC-8853 CRT) manufactured by NEC Co., Ltd. This program enables data on patients to be easily input and instantly expressed. Data input is done by the cursor method, making input very quick and straightforward. Changes, additions and deletions to the data are very easy and output can be made to both display and printer. Data searching is done according to the enquiry and a print out can be obtained at any time for ready-to-read information. The Japanese nation-wide protocol for colo-rectal cancer is used as the basis for the system, providing almost complete linking with the national registry for any stastical data.
