The FILEA sample application programs

The FILEA sample application programs comprise four sets of command-level application programs that operate on the sample VSAM file, FILEA.

Each of the four programming languages that are supported (Assembler, C, COBOL, and PL/I) has its own set. These programs show basic functions, such as inquire, browse, add, and update, that can serve as a framework for your own first programs. They were written before publication of the Common User Access guidelines.

Creating the data set for FILEA

When you submit the DFHDEFDS job, a copy of the data set that the FILEA application requires is created. This data set is installed in the hlq.SDFHINST library.

Making the data set available to CICS

When you tailor the CICS® installation-related jobs, a DD statement for the FILEA data set is added to the CICS IVP jobs and the DFHSTART procedure. If you want CICS to dynamically allocate the data set and open the file, remove the DD statement and install a FILE resource definition with an appropriate DSNAME; for example, as supplied in the group DFH$FILA.
