Header File.....TCXLwin.h

Prototype.......IntT CTYP Wshadow(IntT at);
                IntT CTYP Wshadoff(NOARG);

Source File.....WCT\WSHADOFF.C
                WCT\WSHADOW.C

Arguments.......at -  Attribute for shadow (most effective is _BLACK |
                      DGREY)

Returns.........ERR_NUL  -  No Error
                ERR_ARG  -  Argument Failure
                ERR_MEM  -  Memory Allocation Failure
                   TcxlErr contains:
                   W_NOACTIVE  -  No Active Window

Notes...........Add or remove the shadow from the active window, if one
                exists.  The shadow will be cast to the right of the window
                and will be translucent (the characters underneath the
                shadow will show through in the given attribute).
                Wshadoff() is only needed when you want to prematurely
                remove the active window's shadow.  The Wclose() function
                automatically calls Wshadoff() when it closes a window.
