I am reading an input file and am outputting it in a report format, using the fprintf function .  I have aligned all of the columns under the column headings with the exception of the last column.  

I am having problems aligning the last column. When I enter '%-3s', for example,  the value does not move. How is this done?
See the attachment for the expected output.

In the PNG file you attached, the final column looks aligned correctly.  Are you meaning you want it right-justified instead?

Example 8 on this page may be helpful.

If not, please explain a little more completely where the problem is and I'll try to help.

Currently the last two columns look like this:
SALES DIFF               MESSAGE
   -5THIS IS THE MESSAGE TEXT

Would like them to look like this:
SALES DIFF             MESSAGE
     -5                        THIS IS THE MESSAGE TEXT

I would like to have the final column, right-justified.

OK, how's this?
	fprintf($fout,"\n    %-11s%-12s%3d%25s",$itemID,$itemName,$salesDiff,$message);

Open in new window

I am sorry I misunderstood the question about the column being right-justified.  
I want the columns to align under the column header:

   Message

   The message column text

And I misunderstood your answer.  Sorry about that.

I think we need to right-pad the SalesDiff column with spaces. Let's try ...

	
sprintf($strSalesDiff,"%3d",$salesDiff);
fprintf($fout,"\n    %-11s%-12s%20s%s",$itemID,$itemName,$strSalesDiff,$message);

Open in new window


That should create a properly formatted string that can then be properly spaced in the 2nd line.
