|
||
|
|
|
||
|
|
## Parameter(s)
|
||
|
|
|
||
|
|
* The *stringvalue$* can be any string of [ASCII](ASCII) characters as a [STRING](STRING) variable.
|
||

||
|
|
|
||
|
|
name$ = "Tom Williams"
|
||
|
|
|
||
|
|
Last$ = RIGHT$(name$, LEN(name$) - INSTR(name$, " ")) 'subtract space position from string length
|
||
|
|
|
||
|
|
PRINT Last$
|
||
|
|
|
||
|
|
```
|
||
|

||
|
|
|
||
|
|
```
|
||
|
|
|
||
|
|
Adding the leading zero in single digit [HEX$](HEX$) values using RIGHT to take the right two hexadecimal string digits.
|
||
|
|
|
||
|
|
```vb
|
||
|
|
|
||
|
|
SCREEN _NEWIMAGE(640, 480, 32) '32 bit screen modes ONLY!
|
||
|
|
red = 255
|
||
|
|
green = 0
|
||
|
|
blue = 128
|
||
|
|
|
||
|
|
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.
