Starting with z390 PTF v1.4.01e, z390 now supports COBOL calling z390 assembler using the IBM standard EZASOKET interface. For demo with source code and screen shot using Micro Focus COBOL calling z390 running on Windows Vista visit:

This same interface can in theory be used with COBOL running on any platform including mainframes and Linux connected to z390 SOA server running on any platform supporting J2SE Java connected to the same TCP/IP network.
