Hello, all: I have a (hopefully) rather simple question about OOP. I can grasp the BASIC concepts, but one problem I'm having is determining how far 'down the pole' to define an object. Consider the following non-OOP code (this is from a statistics package I'm currently working on (forgive me if a little Ada code happens to sneak in here :-) )): {--------- 8< --- 8< --- 8< -----------} type roster_size_type = 0..40; hit_stat_type = (GMSPLAYED,ATBATS,HITS,SCORED,HOMERUNS,RBIS,STOLEN); pitch_stat_type = (GMSPITCH,INNINGS,WINS,LOSSES,SAVES,EARNED,STRIKEOUTS); hit_array_type = array [hit_stat_type] of integer; pitch_array_type = array [pitch_stat_type] of integer; player_type = (HITTER,PITCHER); player_record = record name : string; team : string[3]; case ptype:player_type of HITTER : (HSTATS : hit_array_type); PITCHER : (PSTATS : pitch_array_type); end; var player : player_record; team : array [roster_size_type] of player_record; {--------- 8< --- 8< --- 8< -----------} Now the questions. First, what CAN be declared an object? What SHOULD be declared an object? What would be the best way to set this up? I know the team variable can inherit the properties of the player_record type (object), but I'm not sure how any of it should be set up. I would REALLY like to finally take the dive into OOP, but taking the first step is giving me a headache.
