[comp.sys.handhelds] Questions about Casio FX-790P

                    Hello everyone out there !!

                 I have some questions about the 
                         CASIO FX-790P 
                       pocket computer !!!!


A few days ago I bought this calculator (8KB RAM) which is programmable
in BASIC and ASSEMBLER. It it a very nice and handy calculator, but there 
are some points about the ASSEMBLER language where I need some insider 
knowledge.

1.) Although the FX-790P has 8kB and can be expanded to 16kB it seems 
    that one can use only 4kB for the ASSEMBLER program. Is there any
    way around that ?

2.) Is there a way to call an ASSEMBLER program from within a basic program ?
    (Perhaps even passing parameters)

3.) There is an ASSEMBLER command 'READ' which reads input from the keyboard.
    Unfortunately it is equivalent to the BASIC 'INPUT' command, that means
    the program stops and waits for input. Is there a way to read input in 
    an 'INKEY$' like fashion, that means the program tests if a key was 
    pressed without stopping the program ?

4.) Is it correct that this ASSEMBLER language is not the genuine ASSEMBLER
    language of the FX-790P, but a kind of 'model ASSEMBLER language' which
    is actually interpreted ? 
    If yes, is there a way to use the genuine ASSEMBLER language ?


If you have any ideas or comments to my problems please contact me by sending
mail to me directly, because I am not yet connected to NEWSFEED.
