If I understand the flood of information that came my way when I was trying to understand this exact same thing, the LDA is an example of a control block you can access without using an SRB.

I believe the unpredictability comes when the target address spaces are swappable. Depending upon your application requirements non-srb code may in fact work. For example, address spaces with a system LX that support space switch pc routines will always be non-swappable. If your application required data from these address spaces you should be ok. There are other address spaces that normally run non-swappable. However, you could not access all address spaces with this technique. For swappable address spaces you should use SRB code. As usual, it depends upon your application......... ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
