RIGHT$ - QB64Official/qb64 GitHub Wiki

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.

red = 255

Color32 red, green, blue
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.
