Assuming I understand what you're really asking, this is definitely doable.
Here's a small example showing how to invoke an ooRexx program.
https://sourceforge.net/p/oorexx/code-0/HEAD/tree/main/trunk/utilities/rexx/platform/unix/rexx.cpp
This actually uses two different methods, the older RexxStart() API and the
newer object oriented interfaces. I suspect you'll want to use the newer
APIs. For your application, it should be possible to create a single
interpreter instance and reuse that instance to run your code snippets.
This example uses the CallProgram() API which reads the code from a file.
You can also use NewRoutine() to create a Routine object without using a
file and then use CallRoutine() to invoke the code. Note that if you go
this route, once the call completes you'll want to use
ReleaseLocalReference() to let the garbage collector know you're done with
this object. If you don't, all of the code snippets you execute will
accumulate in memory until you app quits.
