Casio FX-702P

The FX-702P is a Pocket Computer, manufactured by Casio from 1981 to 1984.

Display

The FX-702P features a single line dot matrix liquid crystal display with 20 characters. A 10-digit mantissa is displayed (including minus sign) however internal calculations use a 12-digit mantissa.

Programming

The programming model employed is a special BASIC dialect. Ten programming areas are supported, P0 through P9. BASIC lines can be numbered from 1 through to 9999. Subroutines are supported, but passing parameters to subroutines is not supported. The subroutine call stack can be up to 10 deep. Both GOTO lines and subroutines can be addressed indirectly via line number calculation. FOR/NEXT structures can be nested up to eight times.

A single one and/or two dimensional array is supported however array memory space must be reserved (subtracted) from the 1,680 character program space via the DEFM command. Array memory can be aliased to fixed variable names, for example A(11) references the same location as variable B1.
