FT_SAVEATT()
Save the attribute bytes of a specified screen region.
------------------------------------------------------------------------------
Syntax
FT_SAVEATT( <nTop>, <nLeft>, <nBottom>, <nRight> ) -> cAttributes
Arguments
<nTop>, <nLeft>, <nBottom>, and <nRight> define the screen region.
Returns
A character string containing the screen attribute bytes for the
specified region. If the memory to store the return value could
not be allocated, the function returns NIL.
Description
This function is similar to Clipper's SaveScreen(), except that it only
saves the attribute bytes. This is useful if you want to change the
screen color without affecting the text.
*** INTERNALS ALERT ***
This function calls the Clipper internal __gtMaxCol to obtain the
maximum column value for the current video mode. If you're too gutless
to use internals, then this function isn't for you.
Examples
// Save attributes of row 4
cBuffer := FT_SAVEATT( 4, 0, 4, maxcol())
// Save attributes from middle of screen
cBuffer := FT_SAVEATT(10,20,14,59)
