FX-850P memory question - Dan C - 07-03-2022 08:58 AM
I just started up my FX-850P today and its in a very good condition after all this years!
Its the standard FX-850P with 8 KB memory.
I wonder what the FRE0 and FRE1 commands should report back?
FRE0 gives 1510 and FRE1 gives 3536.
Is that correct?
edit. After a CLEAR command the FRE0 gives 1536.

FRE0 is the space for variables that hasn’t yet been used. Look closely at the chart on page 90 and you’ll see it!
