Technical Notes
This Built-In Function allows a function to dynamically change from heavy usage to light usage (and vice-versa). For example:
...
if (*jobmode = B)
...
use SET_FOR_HEAVY_USAGE
else
...
else
use SET_FOR_LIGHT_USAGE endif
At every entry or (re)entry the heavy/light usage option is set by the calling parent process, or adopted from a *DIRECT caller, so at every invocation you should positively (re)set the usage option.
This built-in executes very quickly and imposes little overhead.
