AUI_CONTROL now supports a new parameter, CTYPE2, which is another 32 bit bitmap of flags intended to serve as an extension of CTYPE. Currently none of the values are used, but the top 8 bits are reserved for application-defined bits. Setting these will have no affect on A-Shell, but might be useful for storing flags that you can retrieve via the CTLOP_INFO call. (The top 8 bits would be &h80000000 thru &h01000000.)
