COMMON CICS COPYLIB MEMBERS - IBM Mainframe

This chapter lists two CICS COPYLIB members, which are very commonly copied into the CICS application programs. They are DFHEIBLK and DFHBMSCA, which contain the Execute Interface Block Fields and the attribute characters, respectively, as follows:

DFHEIBLK Member

The DFHEIBLK member is a set of field definitions of the. Execute Interface Block (EIB), and it is automatically copied into a CICS application program by the CICS command translator and COBOL compiler. When CICS activates the application program, it places the proper value into the corresponding EIB fields, and the values will be continuously updated as the program is executed. Therefore, the application program can use these fields freely for the application purposes. The following is the full list of EIB fields included in the DFHEIBLK member and their characteristics:

DFHEIBLK Member

DFHBMSCA Member

The DFHBMSCA member is a standard list of field attributes and printer control characters, which are commonly, used in CICS application programs. An application program must issue the COPY command in order to include this member in the program since this member is not automatically included by the CICS translator and COBOL compiler. The following is the full list of character definitions included in the DFHBMSCA member and their characteristics:
