# Numbering the columns in a lstlisting environment

I'm trying to write some commentary about data that is formatted to a very old standard (ARINC 424) in which each record is a 132-column line and data fields are identified by the columns they occupy.

Thus, I would like to be able to number the columns in addition to the lines in a lstlisting environment, but I can't find any way to do this in the listing package documents.

I was thinking that printing the column numbers along the top of the listing rotated 90 degrees CCW would be relatively readable. Does anyone have any idea how I could implement this?

Thanks in advance. I'm including a MWE but I don't think it's particularly useful since I don't know how to approach this at all.

One way might be to write the column numbers above the first line in steps of 5.

This can be done as part of the lstlisting environment, but then it is difficult to customize - for example not putting a line number or frame, and print the column numbers in gray.

An alternative is to use two listings environments, one for the column numbers and one for the actual code. The floating environment makes this a bit tricky, but you can use the column numbers listing as float and the actual code as non-floating listing. This does not guarantee that the two listings stay on the same page so you need to check this carefully in the final document. The spacing above and below the two listings should also be adjusted using belowskip and aboveskip.

Result:

• Thanks for the idea. I was able to finagle both listings into the same float environment using the float package, and made this new float environment share the listing counter using the top answer to the following question: tex.stackexchange.com/questions/145546/… I also tried using three rows in the first listing with the numerals typed so you can read the number of the column from top to bottom (001, 002, ... 010, 011, ... 100, 101, ...) but that's a lot busier. But it does have the advantage of not needing multiple columns. – jnrobinson Mar 3 at 20:45
