The RIGHT$ function returns a set number of characters in a STRING variable starting from the end and counting backwards.
Syntax
RIGHT$(stringvalue$, numberofcharacters%)
Parameter(s)
- The stringvalue$ can be any string of ASCII characters as a STRING variable.
- The numberofcharacters INTEGER value determines the number of characters to return from the right end of the string.
Description
- If the number of characters exceeds the string length(LEN) the entire string is returned.
- RIGHT$ returns always start at the last character of the string, even if a space. RTRIM$ can remove ending spaces.
- Number of characters cannot be a negative value.
Example(s)
Getting the right portion of a string value such as a person’s last name.
name$ = "Tom Williams"
Last$ = RIGHT$(name$, LEN(name$) - INSTR(name$, " ")) 'subtract space position from string length
PRINT Last$
Williams
Adding the leading zero in single digit HEX$ values using RIGHT to take the right two hexadecimal string digits.

PRINT "Colored text"
SUB Color32 (R, G, B)
R = R AND &HFF: G = G AND &HFF: B = B AND &HFF ' limit values to 0 to 255
hexadecimal$ = "&HFF" + RIGHT$("0" + HEX$(R), 2) + RIGHT$("0" + HEX$(G), 2) + RIGHT$("0" + HEX$(B), 2)
PRINT hexadecimal$
COLOR VAL(hexadecimal$)
END SUB
**&HFFFF0080**
**Colored text**
Note: When a single hexadecimal digit is returned the resulting value will need the leading zero added. Otherwise the hexa- decimal value created will have a byte missing from the value. EX: Color &HFF000000 is valid while &HFF000 is not.
