The preferred method for initiating jobs stored in files on tape is to first copy the files onto disk and then start them. The files can be copied using the WFL COPY statement, either from CANDE or as part of another WFL job. Once the files are on disk, they are started using the CANDE START command, a START statement in another WFL job, or the MARC START command.

If a site is attempting to conserve disk space, the job file can be removed from disk after each use and recopied from the tape whenever it is needed. The job can even include a REMOVE statement that would remove its own job file from disk after each use.
