COPY files
Various COPY files are provided to help you write COBOL application programs that use the MQI. There are two files containing named constants, and two files for each of the structures.
Each structure is provided in two forms: a form with initial values, and a form without:- Use the structures with initial values in the WORKING-STORAGE SECTION of a COBOL program; they are contained in COPY files with names suffixed with the letter V (for Values).
- Use the structures without initial values in the LINKAGE SECTION of a COBOL program; they are contained in COPY files with names suffixed with the letter L (for Linkage).
The COPY files are summarized in Table 1. Not all the files listed are available in all environments.
