Hi Perl Monks,

It might be a silly question but I am at my wit's end to get the desired result in the last array (line 19). I have written a perl script (given below) to count the number of 4-letter fragments in a 15-letter word. My interest is to assign the length of each fragment as an element in the final array i.e. @newarray. The new array at line 19 should show the elements (4 4 4) but I am getting only one 4. Is it possible to get the correct result from the newarray as (4, 4, 4)?

Here goes the perl script:

#!/usr/bin/perl  
use warnings;
$word="ABCDEFGHIJKLMNO";
## Determining the number of 4-letter Fragments:
$a=length($word);$four=4;  # Line 5  
$frag_Num1=$a/$four;$frag_Num=int$frag_Num1;
print"\n Total Fragments= $frag_Num\n\n";
print"\n\n The 4-Letter Fragments are:\n\n";
$frag=0;
while ($word=~ /(.{4}?)/igs)   # Line 10 
 {$frag++;
 $b=$&;$pos=$-[0]+1;
 $leng=length($b);
 print"\n Fragment: $&; Fragment Number: $frag of length $leng letters
+ Starting at position: $pos\n";
 print"\n Its length= $leng Letters;\n\n";  # Line 15 
 $newlist=$leng;
 }
@newarray="$newlist"; 
 print"\n Newarray (should be 4 4 4): @newarray\n\n"; # Line 19
exit;

The cmd has shown the correct results except for the last line:

Total Fragments= 3

 The 4-Letter Fragments are:

 Fragment: ABCD; Fragment Number: 1 of length 4 letters Starting at po
+sition: 1

 Its length= 4 Letters;

 Fragment: EFGH; Fragment Number: 2 of length 4 letters Starting at po
+sition: 5

 Its length= 4 Letters;

 Fragment: IJKL; Fragment Number: 3 of length 4 letters Starting at po
+sition: 9

 Its length= 4 Letters;

 Newarray (should be 4 4 4): 4

The last line should look like:

Newarray (should be 4 4 4): (4,4,4)
