              When built with ncurses, cdialog normally checks to see if it is 
running in an  xterm,  and  in  that  case
              tries  to suppress the initialization strings that would make it 
switch to the alternate screen.  Switching
              between the normal and alternate screens is visually distracting 
in a script  which  runs  cdialog  several
              times.  Use this option to allow cdialog to use those 
initialization strings.

If it's not built with ncurses, it cannot do that.

Alternatively, use a terminal description where the smcup/rmcup capabilities 
are empty.
