HFS files are designed to run in a UNIX environment, you can still access them through a batch job. The JCL you use is a little different, though, than for standard data sets. Zo/s provides some additional parameters for the DD statement that allow you to create, access, and delete HFS files.
A pathname must…
- Begin with a slash.
- Include all directory and subdirectory names that lead to the file itself.
- Be from 1 to 255 characters long.
- Be enclosed in single quotes if it contains any lowercase letters.
- Be enclosed in single quotes if it is continued on more than one line.
A PATH parameter that’s used to access a master file in HFS format
//DD1 DD PATH=’/usr/data1/r1/ab0020/MASTER.file’
A PATH parameter with a long file name
//DD1 DD PATH=’/USR/DATA1/R1/CA0020/ACCOUNTING/REP
Do not code the PATH parameter on any of the following DD statements
- The PATH parameter on a DD statement is used in place of a DSN or DSNAME parameter to identify a file in HFS format.
- Symbolic parameters can be used within the PATH parameter.
- Backward references to a DD statement with a PATH parameter are not allowed and are treated as errors. In some cases, you also need to include the PATHOPTS parameter in order to successfully access an HFS file.
