anyways, i'm suppose to do like program about disease and their symptoms using common lisp.basically the program will ask if the patient have this symptoms or not, the patient suppose to answer yes or no,then the system will just tell the patient of their disease. i did a few try but failed though. so this is my last resort. if none of you guys know.. im not gonna try anymore. haha.. maybe i should give up on LISP and take on VB instead. lol
