Hi Dusty,
I am not sure what the CHAR command does in visual basic. I would assume that this is actually a data type (character) and not a command. If that is true, typecast is sort of similar. You can use type cast to change the representation of a data type to another data type. (Like cBool, cString, etc.).
Hope this helps out.
