Mainframe, MVS and zOS Discussion

There is nothing "non fashionable" about it. Fashionable I wrote. The way it goes is Person A: It's a Legacy System Person B: OK, it's clear we need to get rid of it then, and in the meanwhile blame it for any disasters that we have around here Note that neither Person A nor Person B knows...

Nah. Another fashionable bit of nonsense, bandied about by people who know nothing about Mainframes and who feel that any Mainframe must be at least 30 years old.

It is fashionable fluff and waffle, with no meaningful content.

Memory was never, or rarely, a problem which would lead to the use of binary or packed-decimals. Disk space more so, but not really. The benefits of binary and packed-decimal were, and remain, performance. A USAGE DISPLAY (the default if no usage specified) field has to be converted if arithmetic is...

At the point at which the XDC was successful, what is the message in the top right of your screen?

Ask your technical support team. They will know the procedure they want you to use to do this (even if it means you telephone someone and get them to do it). Attempting to run random bits of JCL picked up from the Internet is unlikely to be the suggested course of action.

Given that you admit to exhausting the available space for typing, how do you feel you'd be able to do it "in a single go"? Use F(ind) for your first "really long string". Then C(hange) * "your other really long string" all If you don't have space for "all", t...

There are a number of ways. You can look at, amongst others to which these should lead you in the manual, STOPAFT and SAMPLE.

They are very different. They use the same name because one comes from nomenclature in the development of the COBOL language in 1959 and one comes from the nomenclature of the development of the idea of the relational database model in the years up to 1970. It is unfortunate, but there it is. Just t...

What do you think the word "passed" means in this context? It is clear that you are wrong about what it means. What is "passed" is the address of the storage. Which means if a 10-byte field is "passed" the address of the 10-byte field is passed. If that 10-byte field is...

I haven't look at the quality of the article, but it should give you some idea.

Well, if your site tells you you don't need to use it, then fine. Otherwise strange and unexpected things will happen. How would any printer (new or old) know how you want something printed unless you tell the printer how you want it printed? Of course, you could take your 30,000-page output and cod...

Just the usual. It is not possible that the enforced corruption of the English language to impose specific gender on non-gender-specific use of specific gender words means that people can't understand each other any more? Sad, but I guess it is possible. I'll note for future reference that whatever ...

You have COBOL V5. The additional functionality provided by OPT(FULL) over OPT in V3/V4 is provided by a new option in V5 (see the last line of the quoted text). So now, in V5, OPT does not remove unused storage, the new option does. What the quote is about is the identification and removal of gener...

Well, your SORT product can do it. Use VTOF (better) or CONVERT and us VLFILL to get your pad-character.

S0C7 occurs only when a Decimal Instruction is used (consult the Principles of Operation) and the data provided does not conform to the convention for packed-decimal data. Note that if the source field is a DISPLAY/zoned-decimal field, you need to apply the consideration of conformation once the dat...

Note, it is not the "length of the file" it is the record-length, an entirely different thing, whatever you think length of the file means.

Compile with compiler option OPT(FULL). If your compiler doesn't support that, look in your Programming Guide to see what to use instead.

To do it without a function, you can look at INSPECT ... CONVERTING ...

A panel to allow a count of the number of records on a dataset? What a waste of resources. You know that someone (likely) pays for resource-usage on the Mainframe? If you want to find out the number of records, don't lose them. Maintain them on a trailer/stats record, and reconcile them each time th...
