[rrd-users] reuse of CDEF var for use in loops

[josef]

Hi Sbnm,
would you please let me know an exampe of "append $cmd and executing outside
the loop" ?

i have created this ressource wasting sript, but it works, and i want to
optimize !

$prev=0;
for ( $x  .... ){ 
 if  ($x > 0){
    CDEF:sum$x=sum$prev,ds$x,+ 
    $prev++;
} else {
    CDEF:sum$x=ds$x,1,*
} 

rgds Josef
