Migration of pre-OS/390 C/C++ applications to z/OS V2R2 XL C/C++

Prior to IBM OS/390®, C/C++ applications were created with one of the following products:
  • IBM® C/C++ for MVS/ESA V3R1 or V3R2
  • IBM AD/Cycle C/370™ V1R1 or V1R2
  • IBM C/370 V1R1 or V1R2
  • IBM C/370 V2R1 compiler and the IBM C/370 V2R1 library
  • IBM C/370 V2R1 compiler and the IBM C/370 V2R2 library
Notes:

  1. If your application uses IBM CICS® information or statements, also see Migration issues with earlier C/C++ applications that run CICS statements.

  2. If your application uses IBM DB2® information or statements, also see Migration issues with earlier C/C++ applications that use DB2.

The following topics provide information relevant to migrating a pre-OS/390 application to z/OS® V2R2 XL C/C++:
