Another method for storing information about job execution is to have the job create dummy files at specified points during the job execution, or whenever certain conditions are met. The job can then use the file residence inquiry to establish whether such files have been created, and make decisions based on their presence or absence.

Refer to File Handling for an example of a subroutine that can be used to create dummy files. The file residence inquiry is described under Interrogating File Attributes.
