There is no a priori limit on the number of PATHOUT or PATHIN statements that can be specified in the COUPLExx parmlib, nor is there an a priori limit on the number of signal paths (devices or structures) that can be defined therein. You would of course eventually hit some sort of practical limit in that these definitions spawn the creation of control blocks, which consume physical resources (such as fixed common storage within z/OS and CF structures within the coupling facility when applicable). The CFRM policy would also indirectly impose practical limits on the total number of XCF signal structures that can be defined, but these would not be discovered until XCF initialization tries to instantiate the signal structures defined by COUPLExx.
I suppose one could conceive of the possibility that the system doesn't have enough storage to construct a representation of the parsed definitions, but that seems improbable.
