Enterprise COBOL for z/OS 6.3 documentation is refreshed today to include the following enhancements:

Enhancements in COBOL 6.3 with PTFs installed: (For a complete list of Enterprise COBOL PTFs, check https://www.ibm.com/support/pages/node/604539):

• Runtime APAR PH59864 (V2R5 or later): When PTFs for LE APAR PH56800 and COBOL Runtime APAR PH59864 are installed on z/OS 2.5 or later systems where COBOL programs run, the AMODE 31 subprograms called by the caller program can be either a DLL or a non-DLL. (Dynamic call between AMODE 31 and AMODE 64 programs)

Documentation fixes in COBOL 6.3:

- In Programming Guide:

• Clarified that for an LP(64) COBOL program to be called dynamically, the program-name in the PROGRAM-ID paragraph must be identical to the corresponding program object name. (Compiling and binding AMODE 64 programs under z/OS)

• Added an example about how to create an application that consists of a COBOL main program that calls a C DLL subprogram. (Example: sample JCL for a procedural DLL application)

- In Migration Guide:

• Clarified that CCCA can convert CICS and non-CICS COBOL source programs and copybooks from old 68 COBOL Standard and 74 COBOL Standard languages to the 85 COBOL Standard language. (COBOL and CICS Command Level Conversion Aid for z/OS (CCCA))

- In Customization Guide:

• Clarified that you need to rebuild your reserved word table using the latest IGY8RWRD or IGY8CICS. (Creating or modifying a reserved word table)

• Clarified the difference between the IGYWDOPT and IGYWUOPT sample jobs. (Sample installation jobs)

• Streamlined and reordered the modifying compiler options defaults section according to the installation flow. (Planning to modify compiler option default values)

The English PDF files are also refreshed to include the updates above. You can find the latest English PDF files from the Enterprise COBOL for z/OS library page at https://www.ibm.com/support/pages/node/611415.
