TS/MP 2.5 System Management Manual

You must also consider whether Pathsend requestors or SCREEN COBOL applications —perhaps
those controlled by remote systems—use hard-coded node names in requests to server processes
that belong to the application you want to migrate. If Pathsend procedure calls and screen
application requests have not been coded for node independence, the applicable code must be
changed manually.
If you plan to switch your application to a new system, and especially if you plan to migrate your
application on a regular basis, you must consider creating an Command file to accomplish any
required manual changes.
