The classic solution to this problem is to have the interactive program
display a screen that asks for the parameters and then submits the job to
batch using those parameters.

 menu option x
  RPG program EXFMT GETPARMS -or-
  CL program SNDRCVF GETPARMS
   SBMJOB cmd(CALL xxx parm(a b c))

If for some reason the batch job MUST run before any interactive job can
submit it (like this is a batch server job that requires different
parameters from different clients) then you can have the batch job wait on a
data queue (QRCVDTAQ API).  Have the interactive jobs send the parameters to
the batch job by the QSNDDTAQ API.

Using a data queue allows multiple servers to listen to the same queue.  You
can also use a message queue as the transport mechanism, but one can only
attach a single listener to a message queue.

You could also have the batch job act as a socket server, listening for
connexion requests from the network.  The clients (the programs sending the
parameters) could be anywhere on the network including on a PC running Java
or *nix!
