RGB - function of language VBScript

Description:
Returns a integer that represents an RGB color value.
In the PROMOTIC system it is better to use the Pm.ColorRgb method.
Syntax:
Long RGB(Integer red, Integer green, Integer blue)
Parameters:
red(Integer) Number between 0-255. Red component of the color.
green(Integer) Number between 0-255. Green component of the color.
blue(Integer) Number between 0-255. Blue component of the color.
Note:
This method is not often used in the PROMOTIC system because the PROMOTIC system has color as RGB String in the form "#RRGGBB".
Application methods and properties that accept a color specification expect that specification to be a number representing an RGB color value. An RGB color value specifies the relative intensity of red, green, and blue to cause a specific color to be displayed.
The low-order byte contains the value for red, the middle byte contains the value for green, and the high-order byte contains the value for blue.
The value for any parameter to RGB that exceeds 255 is assumed to be 255.
Example:
The example will provide the same functionality as RGB function:
