AG> is there a better way of writing this script
this is not a script but a short code snippet. there are many ways to
redo this. many questions could be asked as well.
AG> my @resultss = qw( 0 1 2 3 4 5 ) ;
is that always a fixed list? could @jvalue have more then 6 entries? if
you want all of @jvalue you don't need @resultss at all.
AG> foreach ( @resultss) {
foreach ( 0 .. 5 ) {
or if you want all of @jvalue:
foreach ( 0 .. $#jvalue ) {
and you should use a named var for the loop counter:
foreach $j_ind ( 0 .. $#jvalue ) {
AG> if ( defined( $jvalue{$_}){
AG> $status .= $jvalue{$_} ;
AG> }
AG> }
that part is just getting the defined values from an array. grep is a
way to do that with a list. join can merge them and then you append them
to $status. now we don't even need the loop counter:
$status .= join( '', grep defined, @jvalue ) ;
that is the whole thing in one fairly clear line of code. perl is very
nice this way.
