Character Code Table

The Casio FX/VX/Z series pocket computers use a custom character encoding that includes standard ASCII in the range 0x20-0x7F, half-width katakana in the range 0xA0-0xDF, and mathematical/scientific symbols in the upper ranges.

Model Differences

The FX-850P, FX-880P, FX-870P, VX-4, FX-890P, and Z-1 series all share the same character set, which includes mathematical symbols (Greek letters, superscript digits, set notation) and Japanese katakana. This is the character set documented below.

The PB-1000 uses a different character set that is compatible with the PB-700 series. It replaces many of the mathematical symbols with graphics characters (block drawing elements). Programs that use CHR$ codes above 0x7F may display differently when transferred between these families.

Character Code Table

Characters are shown with their hexadecimal column (top) and row (left side). For example, the letter “A” is at column 4, row 1, giving character code 0x41 (decimal 65).

Character Ranges

Range (Hex)	Range (Decimal)	Contents
00-0F	0-15	Control codes (not displayed)
10-1F	16-31	Control codes (cursor, insert, delete)

30-3F	48-63	Digits 0-9 and symbols : ; < = > ?
40-5F	64-95	Uppercase letters A-Z and @ [ \ ] ^ _
60-7F	96-127	Lowercase letters a-z and ` {	} ~ DEL
80-8F	128-143	Mathematical/scientific symbols
90-9F	144-159	Superscript digits and special notation
A0-DF	160-223	Half-width katakana
E0-EF	224-239	Card suits, arrows, geometric shapes
F0-FB	240-251	Currency symbols, CJK characters, misc
FC-FF	252-255	Reserved (used internally)

Notes

Control codes (columns 0 and 1) are shown in parentheses and are not displayed on screen. They perform cursor and display control functions.
Characters that cannot be typed directly from the keyboard can be displayed using the CHR$ function. For example, to display the summation symbol: PRINT CHR$(132) or PRINT CHR$(&H84).
Character code 0x5C displays as the yen sign (¥) on the pocket computer screen, following the JIS X 0201 standard. This is the same position as the backslash () in ASCII.
Characters at codes 0xFC through 0xFF (decimal 252-255) are used internally by the system and are not defined as displayable characters.
The special characters in the upper range (0x80 and above) appear on the LCD display but may be substituted with different characters when printed to an external printer via LLIST or LPRINT. Consult the printer manual for the printer’s character code table.
