Mainframe, MVS and zOS Discussion

Code is 77 C PIC 9(04) COMP. 77 RESULT PIC 9(04). PROCEDURE DIVISION. 000-START. PERFORM VARYING C FROM 1 BY 1 UNTIL C = 6 ADD 1 TO RESULT END-PERFORM. DISPLAY 'C= ' C ' RESULT= ' RESULT. with results of C= 0006 RESULT= 0005 The test is performed before the execution of the loop and hence these resu...

Your best bet will be to talk to whoever developed that OPSGS3B program to get help. IBM mainframes, like most computers these days, supports the use of different language sets (which are called code pages). There is a French code page, a standard English code page, and a number of variations of Eng...

You'll need to look into which code page you need. Then you'll need to move your email text from instream into a data set with that code page.

It is rare to open one file more than once in a COBOL program. I've done it a few times in my last 48 years of writing COBOL code but the total can be counted on my fingers.

I put "free sas courses" in my search engine and got lots of hits, including some from SAS.com.

Click on Resources at the top, then click on Slideshare and start reading the slide shows. You can also click random links to see what they are talking about. The only way to start is to click something.

sas.com will have some materials. Note that there is little difference between SAS on a PC and SAS on a mainframe. The only real difference is use of DD statements and their associated options.

Since there are international standards for the COBOL language, the main differences will be the platform being used, the options available and how they are specified. I have taken mainframe COBOL programs, made a few minor tweaks (screen handling on a PC versus file I/O on a mainframe) and run them...

You will get much better results by specifying some more detail about what you want to learn. Mainframes encompass hardware and software, and hence you need to specify what you want to learn. Learning about the hardware management console, for example, will be a very different experience than wantin...

Assembler program? COBOL program? PL/I program? Some other type of program? The message means that you did NOT tell the compiler that you have EXEC SQL statements in your code, and hence the compiler did not prepare your program correctly. Go back and set the SQL directive in the compile JCL (or pro...

The U means this is a USER abend, as opposed to a system abend. As a user abend, you MUST determine which application generated the message and consult it for help. The CAPE on the message ID indicates that you are using a vendor product, so I recommend you contact that vendor for help. And do NOT p...

This would be a good starting place:

Get your friend's help to code up the REXX -- I don't use it often enough to provide any assistance.

You define the records that belong to a group using an appropriate combination of BEGIN=(logexp), END=(logexp), KEYBEGIN=(field) and RECORDS=n parameters. A group is whatever you need it to be -- it could be based upon the values in a particular column or columns, for example. WHEN=INIT applies to ...

From the z/OS DFSORT: Getting Started manual: WHEN=INIT: Use one or more WHEN=INIT clauses to apply BUILD, FINDREP or OVERLAY items to all of your input records. WHEN=INIT clauses and WHEN=GROUP clauses are processed before any of the other IFTHEN clauses. WHEN=GROUP: Use one or more WHEN=GROUP clau...

What is the operator's concern -- the number of jobs in the system or the amount of spool output? Talk to your site support group about using a MSGCLASS that does not retain the output on the spool. If your site has a product that supports batch processing of spool data, you MIGHT be able to do what...

Does the Excel sheet have more than one worksheet? If so, you most likely will have to treat each worksheet as a separate mainframe data set. If it has one worksheet (or for each worksheet of a multi-worksheet file), convert the worksheet into a comma-delimited file on the PC, transfer the .csv file...

Well, that depends partly on the format of the data set. For a VSAM KSDS, you can program a DELETE command for the key of the bad record. For a VSAM ESDS or other sequential data set, you copy the entire data set to another one, omitting the bad record. Copying it back to the original location is op...

Windows and Linux machines open files as well -- but implicitly for the most part. COBOL being well over 50 years old needs the open explicitly stated.

You probably need to change the XDYNAMIC data set to a PDSE instead of a PDS.
