From a novice to a novice: I was recently using the TC and their unix shell environment to write a program for school. My bug was due to some arithmetic I was performing to calculate the address of my next struct member. If you are doing a "straight" list implementation then this is probably not your problem. (but in the event it relates...) The thing that tripped me up was my cast of the pointer before I did the math on it. I cast it as unsigned when it should have been unsigned long. (i.e. the top of my l.word was being chopped off.) The symptom to this problem was a linked list going ALL OVER THE PLACE. Hope this helps... if it doesn't, oh well. dk smith__________________________________________________________
