****** HOW TO ENTER BASIC CORRECTLY *******
                                           
   ALL DIRECTORIES SAY WHAT
RETURN ADDRESS IN BASIC REPRESENTS REGISTER
YOUR PAIR HL`, SO AT THE VERY BEGINNING OF THE PROG-
I RECOMMEND TO INSTALL THE FOLLOWING FRAME:       
                                           
   EXX                                     
   LD (ADR_RET),HL                       
   EXX                                     
                                           
BEFORE GOING TO BASIC PUT THIS:   
                                           
   EXX                                     
   LD HL,(ADR_RET)                       
   EXX                                     
   LD IY,#5C3A                           
   IM 0                                  
   EI                                      
   RET                                     
                                           
   ADR_RET DEFW 0                       
                                           
   OR IT CAN BE MADE EVEN EASIER. DON'T REMEMBER-
NAT HL` IN A SPECIALLY DESIGNATED CELL A
BEFORE LEAVING, GIVE THE FOLLOWING:
NITY OF TEAM (OF OF COURSE WITH THE SUBSEQUENT PEN-
SWITCHING TO IM 0 ):                     
                                           
   LD HL,10072                           
   EXXAND ELSE: IT WOULD BE GOOD AT THE BEGINNING OF YOUR PROGRAM
SAVE THE FRAMEWORK IN SOME VARIABLES
A COUPLE OR THREE VALUES FROM THE STACK, AND BEFORE YOU -
ENTER THEM IN THE REVERSE SEQUENCE
ITEMS ON THE STACK. (ALTHOUGH IF YOU ARE ABSOLUTELY
BE SURE THAT YOU HAVEN'T FORGOT ANY ONE IN THE STACK
VALUES OR WERE NOT POCKED FROM THE STACK BY ERROR
NOTHING EXTRA, SO YOU MAY NOT TAKE
THESE PRECAUTIONS)
