Some day I designed a large ASSEMBLER program which needed to
read some QSAM files, and I soon discovered that the out-of-line branches
imposed by the EODAD processing violated the clean structure of the program,
because the input logic of the many files which were read in parallel
was somehow
Team, I'm currently out of the office. I will return on Monday Dec 19, 2011. If
you need immediate assistance while I’m gone, please contact my manager (Peter
Moir). Otherwise, send me an email message and I will respond when I return.
Thank you, Greg Bowers

To solve this problem, I ended up with a GET routine for every QSAM dataset,

Hmmm. Are you advocating use of semiprivileged instructions

Where does one draw the line?

Once your minimum supported operating system enables use of a particular
semi-privileged instruction, then you can use it just the same as you would any
new macro-based system service provided by that same level of the OS.

Yup,
But the last time I tried it MVCOS was (much) slower than an EXecuted MVC.
Don't remember how it compared to a MVCL(E). But it xould help out if you might
need to move more than 256 bytes but not more than 4096 bytes.
