   Shouldn't make any difference. The order of the two preparatory calls is   
   interchangeable.

   I am not sure what are you trying to say here. This takes LO/HI bytes of   
   an address. Assembler takes care of both being correct.

   One needs to CLOSE() (or CLALL() in some cases) files that were   
   previously OPEN(). Not needed for SAVE().
