05.07 OBJECT-TIME TAPE ASSIGNMENT
The assignment of units by the Loader for use by the object program depends on three variables:
- The channel and unit arrangement at each installation.
- The configuration of the SYStem units table at the time of the object-time assignment.
- The object-programs' requested assignment.
The procedure by which the Loader assigns specific units to the various object-time files based upon the above variables is discussed in Section 06.02. Without prior knowledge of how the assignment is made for each job, the machine operator will have to wait for the tape mounting instructions given by the Loader before he can mount the tapes to be used by the object program. However, prior knowledge may be obtained by one of the following:
- Repeated running of the object program without changing any of the above variables.
- Understanding the method by which the Loader makes unit assignments. The method is simple and can be easily learned.
- If a 1401 is available, a program can be written for the 1401 that will give the operator tape mounting and running instructions for the batch of jobs being card-to-taped on SYSIN.
