Controlling the Location of Files

When using SourceConnect to access source files on a mainframe, there will be files you want SourceConnect to read from and write to on the mainframe, but also files that you want to keep locally. SourceConnect uses mechanisms to enable you to control which files are based on the mainframe and which are workstation based.

When you edit your configuration to specify the mainframe files you want to be able to use, one of the entries you add is extensions. A file on the workstation with an extension specified in an extensions entry will be accessible on the mainframe as appropriate.

To decide whether or not a file is to be accessible on the mainframe:

• SourceConnect first checks the drive the file is on. If the drive is logically specified in a drive entry in the configuration, the next process is to check the extension of the file.
• If the file's extension is specified by an extensions entry (or specified by the extensions parameter of a Panvalet, PDS or Librarian system entry), the file is read from or written to the mainframe.
• If the extension is not specified in the configuration file, or is not line sequential, it is read from or written to the current working directory instead, preserving the existing files on the mainframe.
