output problems again!

Hi all, I'm still having a problem with my output, if you can help? My current program is collecting numbers and doing a calculation which is all fine.  However, I have a problem with the spacing in the output file.I'm only dealing with the "NEWFILE" output here in my program.  My current output looks like this:

  1(E)( 95.58)A  2(E)( 24.87)Q  3(E)( 46.58)T  4(E)( 46.25)V..(etc)....10(E)( 23.33)L  11(E)(0.00)I  12(E)( 35.55)K  13(E)(  0.00)A  
14(E)( 35.76)D  15(E)( 44.55)K...(etc)......164(E)( 15.07)T  165(E)(  6.04)I  166(E)( 15.29)G  167(E)( 23.14)Y etc

This is fine but the problem is the spacing between the entries. I currently have 2 spaces between each entry eg 2(E)( 24.87)Q and
3(E)( 46.58)T.  However, because I have 1 digit before the, eg (E), 2 digits and 3 digits the spacing gets mixed up. I need an output format with the same distance between the start of one entry and the start of another. Eg like :1(E)( 95.58)A  2(E)( 24.87)Q if there is one digit before the(E), 10(E)( 23.33)L 11(E)(0.00)I if there are 2 digits before the (E) and like 165(E)(  6.04)I166(E)( 15.29)G if there are 3 digits before the (E).

I think its just a matter of changing the   "printf NEWFILE "$residual($A)(%6.2f)$AA  ", $calcval;" line...I hope you can help!

     my $A=substr($line, 9, 1);
     if ($Reset =~ /\*/) {

          $calcval = ($ACC / $vals{$AA}) * 100;
     printf NEWFILE "$residual($A)(%6.2f)$AA  ", $calcval;

     if ($calcval > 25) {  ## store the values only if the calculated value is greater than 50

sorry, that should be an output like this:

1(E)( 95.58)A  2(E)( 24.87)Q if there is one digit before the(E),
10(E)( 23.33)L 11(E)(0.00)I if there are 2 digits before the (E) and like
165(E)(  6.04)166(E)( 15.29)G if there are 3 digits before the (E).

apologies ....for the third: 165(E)(  6.04)I166(E)( 15.29)G if there are 3 digits before the (E).

This is ridiculous I know....but what I need is always 4 spaces altogether between the last letter entry in the example and the start of the open bracket like this for example:
 1(E)( 95.58)A  2(E)( 24.87)Q 10(E)( 23.33)L 11(E)(0.00)I 165(E)(  6.04)F 166(E)( 15.29)G165 (E)(  6.04)

You want the first number to occupy 3 spaces irrespective of the number of digits it has.

printf NEWFILE "$residual($A)(%6.2f)$AA  ", $calcval;

printf NEWFILE "%3d($A)(%6.2f)$AA  ", $residual, $calcval;

This line should do that trick for you.
(You are telling printf to reserve 3 spaces for $residual irrespective of the number of digits in it)

Check the output with this and let me know if I misunderstood your requirement

Well, if you need 4 spaces and not 3 as was my previous understanding, you could use the following:

printf NEWFILE "%4d($A)(%6.2f)$AA  ", $residual, $calcval;

That greats great..christ, if I'd spotted and solved this problem earlier I'd be a much happier man now!  Thank you!
