When pressing BACO (the name comes from Base Conversion), the calculator waits on input for representing a binary in
any of the four modes DEC, BIN, OCT, HEX in all modes at
once.
First print the input digits, append h, d,
o or b as usual (alpha mode is already set), then
press ENTER. That displays the number in all four number bases and
leaves it on the stack in current base mode whenever the
screen is left with OK or ENTER.You see such an example in the screen-shot. If the
binary is too long, the screen can be srolled. The little arrow at the
screen's right margin indicates in which direction. If no h, d,
o or b at the input digits was appended, BACO does
the most reasonable it can do: it completes the input with the indicator of
the current number base which is always displayed in the header. Clearly, if # 1A is in the edit line and
you are currently in DEC mode, ENTER errors because A is a
digit only in the HEXA system. In this case, the base indicator h must
be written at the end of the input line so that it looks like # 1Ah. Only this
gives BACO complete
information for starting the conversion.
Example. Assume our ancestors had accepted the Octal system (which would have been of great advantage in every respect). When we would have the "Millenium 4000"? Print 4000 and append o so that you have # 4000o in the input line. Press ENTER and you see that would happen anno 2048.
What is the advantage of BACO? Clearly, you may put a user binary on the stack, invoke the the BASE menu und cyle through the different representations sequentially with the menu keys. But BACO can be used inside another program. For instance, to end it with the BACO screen,
