A ArrayArray

B bool (INT)Boolean(Integer)

By unsigned char (byte)Unsigned characters(Bytes)

C charCharacter(Bytes)

CB count of bytesBytes

Cr color reference valueColor(Reference)Value

Dw dword (unsigned long)Double-Character(Unsigned long integer)

F flags (usually multiple bit values)Flag(Generally, there are multiple digits.)

FN FunctionFunction

G _ globalGlobal

H handleHandle

I integerInteger

L longLong Integer

LP long pointerLong pointer

M _ data member of a classData member of a class
