    Hi Dwoolnright,
    Thanks for this great help. Could you please create some tutorials for Assembler macros?

    Hi, Dwoolbright; I am taking your video courses which are much better than the other ones I found from youtube. Just want to say a big THANK YOU for all these video courses!

    Eric.

    Amazing content! The best part is you explained it in a very simple way that anyone can easily understand. THANK YOU for sharing your valuable knowledge.

    This is a comment with feedback on chapter-3.pdf of your book draft at https://punctiliousprogrammer.com/starting-assembler/ (which doesn’t seem to have replies enabled.)

    As an experienced mainframe developer, the column restrictions required for mainframe assembler are probably second nature to you, but they weren’t so obvious to me.

    I tried cut and pasting your sample code from the pdf and assembling it, and immediately hit a number of problems, because the cut and paste from pdf to text format resulted in all the carefully tuned spaces of your sample being lost. I’d adjusted the spacing after the cut and paste manually, but did not appreciate just how picky the assembler would be about spaces. Examples:

    1. The END ASMSKEL, ended up in column 1, which the assembler did not appreciate.
    2. Continued lines had to start in column 16 (I’d incorrectly put them in column 10.)
    3. The continuation ‘X’ characters had to be in column 72 (I think that I’d used column 71 erroneously.)
    4. The DCB parameters had to be in column 16, but some other things had to be in column 10.

    Note that I was using the Dignus assembler with the LzLabs runtime running on Linux (i.e.: not using an actual mainframe for either assembly, nor runtime), but I’d guess that the columnar issues that caused me trouble are probably common to Dignus and the mainframe assembler.

    In this intro chapter, I’d strongly suggest that you detail the column requirements for various parts of the program. If you did so, it would help out clueless newbie’s like me attempting to learn a bit of zos assember (I have a 30 year Linux and Unix history, where expectations of specific column requirements seems completely insane — provided one isn’t trying to use an abhorrent language like python.)

    ps. The email address listed on your http://csc.columbusstate.edu/woolbright/ page appears to be invalid.

      Thanks, Peeter, for taking time to write.
      – There are formatting requirements listed on page 8 in Chapter 3. I wonder if you have an older version of that chapter?
      – Cutting and pasting the pdf is a problem. I’ll add a link to a text file that contains the sample code. I’ll also look for other chapters that need links to other code.
      The email address on my academic site is good. Just in case, it’s woolbright_david@columbusstate.edu

        Once I got the program running, I continued reading, and sure enough found the column requirements detailed. They were along with text that said “try this yourself”, which I’d already done. The link for text download will probably be helpful for others.
