solved apologies wasting peoples' time, comment on compiling verbose made me realize i'm using 91% available, had 0 in 1 of calculations! i've been working on arduino sketch number of years, adding more variable declarations. upped size of array of longs 24*70 24*100 , seemed cause unexplainable errors. (i have many other arrays biggest.) i decided count how many bytes approximately declaring in sketch , counting bigger array structures came approximate number of @ least 14,000 bytes (taking account longs 4 bytes etc). how possible? other 6000 bytes being stored? should add i've been using number of years, upping of bytes used 14 kb approximately 17 kb caused bugs.
