Old Method

To illustrate how prior versions of Control-M solved this problem, consider the daily arrival of IRS tape number 123456.

Figure 373 Illustration 1A: How Control-M Formerly Handled A New Tape

The illustration above represents the one-time definitions required to prepare Control-M for handling the IRS tape.

1. JOB A requires input of the IRS tape number before it can run. The job must be defined in a Control-M table with an IN prerequisite condition of IRS-TAPE-ARRIVED.
2. The JCL for JOB A must include %%LIBSYM and %%MEMSYM control statements pointing to the AutoEdit Library CTM.LIB.SYMBOLS and the AutoEdit member TAPES.
3. The AutoEdit member TAPES contains several AutoEdit parameters (from various jobs), including the parameter %%IRS_TAPE.

On a given day, the Manual Conditions file created by the IOALDNRS utility indicates that the prerequisite condition IRS-TAPE-ARRIVED must be added manually by the user. This serves as a reminder to the operations personnel that a job is waiting for an IRS tape number. When the tape arrives, the user must perform two steps, as illustrated in the following figure:

Figure 374 Illustration 1B: Steps Formerly Performed by the User

1. Access the AutoEdit member TAPES and assign value 123456 to the %%IRS_TAPE parameter.
2. Enter Screen 7 to manually add condition IRS-TAPE-ARRIVED.

When the condition IRS-TAPE-ARRIVED has been added to the IOA Conditions file, and assuming all other runtime conditions are met, the Control-M monitor submits the job. When the job is submitted, the value of %%IRS_TAPE in the JCL of JOB A is updated by the value in the TAPES member. The job parameter VOL=SER=%%IRS_TAPE resolves to VOL=SER=123456.
