in thread using split on every element in an array

Every element of an array is a named scalar variable.

Eg. $array[3] = 'something';  $var = $array[4]; etc.

You can therefore use them directly with split.

Eg.

for my $element (@array) { my @bits = split "\t", $element; #do something with the bits. }

The contents of @array will remain unmodified for further use later unless you assign something to $element.

It might be clearer to you written this way.

for my $index (0 .. $#array) { # $#array is the numer of the highest e +lement. my @bits = split "\t", $array[$index]; }

The first version is usually considered better though.


Examine what is said, not who speaks.

The 7th Rule of perl club is -- pearl clubs are easily damaged. Use a diamond club instead.
