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
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 Function executes very quickly and imposes little overhead.
- Changing a "light usage" function to have a "heavy usage" capability may be more complex than simply adding a use of the SET_FOR_HEAVY_USAGE Built-In Function. Since a heavy usage function's variables and lists retain their values between invocations, more complex entry and/or exit logic may be required.
