If your product will allow for user exits that can be written in a
language that compiles to LE environment code (e.g., COBOL, PL/I, C), or
if your product needs to invoke functions in the LE runtime library,
then before such code is invoked from your product there must be an LE
environment established. There is overhead in repeatedly establishing
an LE environment, so if this were a process that was required many
times in the course of a single execution of your product, you would
probably want to establish that LE environment once even though most of
you product might not require LE.
If you don't have to interface with other code that requires an LE
environment or use LE-runtime functions, and develop your own code in a
language that doesn't compile requiring LE runtime, then you don't have
to have an LE runtime environment for your product.
