StrCat(tmp, rec.size);
FldSetTextPtr(field, tmp);

tmp is allocated on the stack. As soon as this function returns to its called, the space holding tmp is going to be reused to hold other variables. You need to pass the address of a global variable or dynamically allocated memory to FldSetTextPtr in order to avoid having your field be redrawn with garbage.

/* the following works but i need "max: " infront */
FldSetTextPtr(field, rec.size);

This works because the record's size field sticks around later.
