BPX4PCT (pfsctl) example

The following code conveys a command to a Physical File System named ACMEFILE. ACMEFILE doesn't really exist; to actually run this example you would need a real PFS product that supports this function. For the callable service, see pfsctl (BPX1PCT, BPX4PCT) — Physical file system control. AMODE 31 callers use BPX1PCT (pfsctl) example.
