So is using the NULL type of delimiting faster or using
Char var1 = "test";
Char var2 = 25";
typedef struct
{
Char name[64];
Char level[64];
} QuestType;
QuestType Appt:
StrCopy (Appt.name, var1);
StrCopy ( Appt.level, var1);
blah, blah, blah.........
this would make reading back the record easier, but seems it would
have limitations and some wasted memory space. But you would allways
know the offset IE names data 0-63 levels data 64-127
