Tasks 

1. Find your library INSXXX1.INS2000.FIRSTLIB which was created in connection with Assignment 3. It will have members called BKFAST, DINNER, LUNCH, AND SNACK. Using any technique you wish, list, print, or display the records in LUNCH in order to find out the sequence numbers of each of the records. (The sequence numbers will have six to eight digits each.) You will need to know the sequence numbers of the records BOLOGNA SANDWICH and MILK for the next step.
2. Create a job in a library member called INSXXX1.INS2000.JCL(SCRATCH) that uses utility IEBUPDTE to scratch (delete) the records for BOLOGNA SANDWICH and MILK. (Use the job in Figutre 5.13 for guidance in constructing this job.) After the job has run successfully, print the member to show that only ICE CREAM and BBBBBBBB remain in the member LUNCH. 
3. Use any technique you want to delete member DINNER from the library INSXXX1.INS2000.FIRSTLIB. (You need not turn in a printout showing how you did Step 3.) 
4. Create a new library called INSXXX1.INS2000.JCLJOBS and give it 10 tracks of space with 5 blocks for the directory. Write a job in a file called INSXXX1.INS2000.JCLJOBS(COPY) that uses the IEBUPDTE utility to copy the member called SNACK from the library INSXXX1.INS2000.FIRSTLIB to the library INSXXX1.INS2000.JCLJOBS. Use the job in figure 5.16 for guidance. Ask for a printout of all records in the member in connection with the member copy operation. 
5. Now we will take the job you created above (INSXXX1.INS2000.JCLJOBS(COPYJOB)) and turn it into a PROC. First, though, we need an appropriate place to put the proc, so use any technique you wish to create a library called INSXXX1.INS2000.MYPROCLB. Give THE LIBRARY 15 tracks with 5 blocks for the directory. (You need not turn in anything that shows how you created this proclib.) (Note: The real proclib is called SYS1.PROCLIB, but we do not have the authority to add PROCS to the live system proclib. Thus, we are creating our own (MYPROCLB) to play with, even though we can not actually execute PROCs from it.) 
6. Now build a job called INSXXX1.INS2000.JCLJOBS(MAKEPROC) by following the guidance in Figure 8.4. The PROC will be called COPYMEM and will be nothing more than the job you created above (INSXXX1.INS2000.JCLJOBS(COPYJOB)) modified into a PROC. Some important points to consider: 

• PROCs do not contain input statements like SYSIN DD *. These statements have to be manually placed at the end of the jobs that actually execute PROCs, as shown in the example in Figure 8.14.
• Think. Remember, the example code is only that -- an example. You will have to modify it according to the task at hand here.
• Use symbolic parameters for the name of the input library and the output library. Call them INLIB and OUTLIB, respectively. (You can hardcode the name of the member being copied.)
• Put some comments into the PROC that explain the meaning of the symbolic parameters, as was done in the example in Figure 8.7.
• To be sure your PROC was created correctly, use a utility to look at INSXXX1.INS2000.MYPROCLB(COPYMEM) to be sure it is there and that it is correct. 

• Printout showing the contents of LUNCH after two records were deleted.
• Printout showing SNACK as a member of INSXXX1.INS2000.JCLJOBS
• Printout of the job INSXXX1.INS2000.JCLJOBS(MAKEPROC) showing that it placed the PROC into MYPROCLB correctly.
• Printout of the job that would run the PROC (INSXXX1.INS2000.JCLJOBS(RUNPROC)). 

Evaluation 

                    PROC COPYMEM successfully placed into INSXXX1.INS2000.MYPROCLB 5 points

                    Job to run the PROC INSXXX1.INS2000.JCLJOBS(RUNPROC) correct. 2 points
