FX-602P $WikiTagline
 

The following is a list of the internal steps used. The FX-602P was advertised as a calculator who fully fully merges as oposed to early programmable calculators did not merge steps and then "inv sin" would have been two steps. This is course is a great waste of – at the time – precious memory.

The FX-602P – like many modern programmable – calculators merge multiple key strokes into a single step. Each step of course equals one 8 bit value. Since the FX-602P has more then 256 operations it was not possible to merge them all into one 8 bit step. Casio decided to use 3 additional token planes which are activated by the suogates $2C, $2D and $2E. Another plane containing the alpha text is activated and deaktivated by matching pair of $2B tokens.

Standart Plane

The standard Plane contains most of the operations and each operation from the standard plane needs only one step to be stored inside a program - This makes FX-602P programs very memory efficient as the commands from the other planes are almost never used.
