I have not used it before.
IBM's HLASM Toolkit has/had the Program Understanding Tool (PUT) that runs on Windows and uses ADATA to produce control flow diagrams and such. I played with it some years ago, and found that it was not capable of understanding some common techniques such as branch tables, and so was of little use for the code I wanted to look at. But it might work for yours. I've heard nothing about PUT for a long time, and don't know if it's been maintained. Tony H.
