Factoids about M
- The M ways that can affect the value in a local or global variable are: M/FOR, M/KILL, M/MERGE, M/NEW, M/QUIT, M/READ, M/SET, M/NEW, M/TRESTART, M/TROLLBACK, passing as an argument using M/DO or $$ or M/JOB, the $INCREMENT function, and of course, any implementation-specific semantics such as M/BREAK, M/CLOSE, M/OPEN, M/USE, M/VIEW, Y* and Z*
There are other ways SSVNs and Intrinsic variables can be changed not listed here.
