We know how to use Node.js to *expose* RESTful APIs on the IBM i. However, if we want to consume an API from a COBOL or CL program, we only know of one way to call a Node.js script: use a QShell command. The QShell command does not appear to have a way to return data from the Node.js script. We can’t get the data from the API we want to consume. We thought about having the Node.js script consume the API and write the data into a database file or data queue, which would then be available for processing by the COBOL or CL program. But…ugh! It just seems like a clunky workaround.

It is clunky. There is no CALL/PARM interface between RPG/Cobol/CL and
the PASE open source languages. That said, Scott Klement has a utility
called UNIXCMD that makes these cross-PASE interactions much easier.
Basically, it uses standard pipes to connect the two end points. It's up
to both sides to format/understand the text passed down the pipes.
