PoOPS in the “Summary of Changes” sections usually have at least some listing (in text format, nothing tablularized or easy to pick out) of instructions added in each manual section, but sometimes those are “generic” and don’t include all the variations of added instructions.
The only way I can think of to accurately (more or less) track the additions would be to extract the Appendix B instruction table that is in OPCODE order to a text format file and then compare each edition’s table to the prior edition’s table. I can say from personal experience that the “pdftotext” command-line utility available from the XPDF project ( https://www.xpdfreader.com/ ) (which is NOT the “pdftotext” version normally included in many linux systems) for Windows execution works pretty well on most editions of PoOPS once you use the right command-line parameters. Once extracted to pure text the tables are at least in a manipulable form that a subsequent text tool can massage into a format you can use for comparisons and extraction of “differences”. But truthfully the OPTABLE lists are probably the easier solution. Just run a separate assembly with each OPTABLE value and massage the output to make the columns of instructions into one-line-per-instruction format and you will be able to compare each generation to the next. SMOP, and (g)awk or python would be a reasonable tool to do the text manipulation needed.

I thought PoP used to have something similar but I don't see anything back to Revision 7 (oldest copy I have). -- This message and any attachments are intended only for the use of the addressee and may contain information that is privileged and confidential.
