Is there a reason why ksh -n triggers a warning (( x=$y )) about efficiency but $(( x=$y )) does not?
> ~/bin/ksh -n -c 'float x=1 y=2 ; (( x=$y )) ; ' /home/ced/bin/ksh: warning: line 1: variable expansion makes arithmetic evaluation less efficient > ~/bin/ksh -n -c 'float x=1 y=2 ; : $(( x=$y )) ; ' Ced -- Cedric Blancher <[email protected]> Institute Pasteur _______________________________________________ ast-users mailing list [email protected] http://lists.research.att.com/mailman/listinfo/ast-users
