SKEDFILE

Scheduled McIDAS-X commands.

This binary file has 7172 words and is divided into two sections.

The first section contains basic directory information for the scheduler entries. The scheduler (SKED) uses this section to quickly scan all entries to decide which are due to run.
The second section contains additional directory information and the text of the McIDAS-X command for each entry. This section is read when listings are made or a command is ready to run.

The file division is invisible to all parts of the schedule system accessing the file via the ID number.

For scheduled McIDAS commands Application Program Interfaces (APIs), refer to the API functions list at the end of this section.
