FT_ISBITON()
Determine the state of individual bits in a number
------------------------------------------------------------------------------
Syntax
FT_ISBITON( <nNumber>, <nBit> ) -> lResult
Arguments
<nNumber> is an integer for which a bit state needs to be checked.
<nBit> is a number from 0 to 15 that indicates which bit to test.
Returns
.T. if the specified bit was on., .F. if off.
Description
This function is useful when dealing with binary integers. It will
come in very handy if you use the FT_INT86() function, because the
CPU flags are returned as a series of bits. Using this function, you
can determine the state of each CPU flag.
Examples
if FT_ISBITON( nCPUFlags, 0 )
Qout( "The carry flag was set." )
endif
if FT_ISBITON( nCPUFlags, 7 )
Qout( "The sign flag was set." )
endif
