I found out the hard way that, if you code EXECUTABLE=YES of the STORAGE OBTAIN, you must also code it on the associated STORAGE RELEASE. Evidently, it's implemented as a subpool under the covers, so like subpool getmains, you must have matching values on OBTAIN and RELEASE.

The default is YES, and for earlier releases there was no execute-prevention capability afaik. I don't know what to tell you about the "security model". It's a big subject. sas On Mon, Nov 16, 2020 at 12:24 PM Ze'ev Atlas < 000001774d97d104-dmarc-requ...@listserv.uga.edu> wrote: > Hi allIn the 1970's I probably could have done some getmain, write > some code into that obtained memory and jump to that code.
