Calling a main routine

When calling a main routine, additional runtime options are passed as a string of characters on the call. This string is merged with the initialization runtime options string, the application runtime options settings found in CELQUOPT, and the system-level defaults, before initializing the environment. For more information, see Creating a user-managed environment.

Each time a main is run within an environment, CELAAUTH reinitializes the environment. This includes:

Refreshing the main's WSA
Resetting Language Environment component states
Cleaning up unneeded heap allocations from a previous use
