(Warning: advanced information :-)

The JPC ROM has provision for executing non-programmable functions, with the EXECUTE command.
There is an additional difficulty: after executing CLAIM/FREE ports (that causes system reconfiguration), the current program is ended and the current program file is set to 'workfile'. But is is easy to manage it by adding a RUN command after the CLAIM/FREE to continue the program.
For instance, create the TEST program file:
10 ! TEST
20 DISP "Doing EXECUTE..."
30 EXECUTE "FREE PORT(5) @ RUN TEST,40"
40 DISP "Done."
