Line commands in mainframe

We'll introduce you to the hardware and peripherals. We'll talk about the operating system, the software installed on a mainframe. We'll also talk about the different people who work on a mainframe.

In a nutshell, we'll de-mystify the mainframe. Readers based in Indiacan buy the e-book for Rs. International readers based in the US and other countries can click here to purchase the e-book.

You enter Primary-Commands on the command-line. Line Commands apply to the current-line or Block-of-lines. If you are a Windows or Linux user, beware! If you want to type some more text on the Next-line, you must first insert a new blank-line manually. Life ain't easy on Mainframes.

To many people who are thrown to work at a mainframe computer on their first job, they feel lost. Mainframe people seem to speak a completely different language and that doesn't make life easy. What's more, the books and manuals are incredibly hard to comprehend.

Accompanied with Move and Copy, you also need to tell, the position or destinationwhere the Line is to be Moved-to or Copied-to. Use a second-command to tell where to place the line-of-text — Before B or After A a destination line-no.

View previous topic :: :: View next topic. Myself is Utpal. I want to know for line by line execution which PF key is used in Expediter. If you send the answer i will be thankful to you.

Back to top. Utpal To execute line by line we use the key F9. After this press F The execution will stop as soon as A gets value as 'xyz'.

After this do not forget to give "delete when" command. If one program calls second then you can view source for the second program from first by SO command. But I thing these are the mainly used commands and sufficient for debugging programs through expeditor. HI I am little bit aware of Xpediter but I am muddled of how to execute a program if it is having sub programs Hi AjayVamsi!

I am little bit aware of Xpediter but I am muddled of how to execute a program if it is having sub programs Hi All! Here are few more Expeditor commands. We generally use only few of them. I too didn't try some of the commands. HI Anu, Thanks a lot for ur patience.!!After you display a data set list by leaving the Option field blank, you can enter a line command to the left of the data set name.

You can type over the field containing the data set name to enter commands that require more than the space provided. You can also enter line commands in block command format to execute the same line command for several data sets at once. You can enter several blocks of commands at the same time, but you cannot nest them. Single line commands are not allowed within a block command.

Line commands that are valid for aliases may be used with any alias data sets that are listed. Uncatalog, delete, and rename commands are not valid for alias data sets. A line command such as 'B' for browse or 'I' for information will display the real name of the data set. See Table 1 for the list of those variables.

If bounds are on, only the data within the bounds is sorted and moved; other data is not moved. This is a way to sort columned data separately. Sort lets you sort fields in either ascending or descending order.

The maximum number of sort fields is five. When using multiple fields, both start and end columns must be provided. Default is ascending sort. If one field specifies ascending or descending, all fields must specify it. Here are a few examples:. SORT 10 sorts from column 10 to the right bound. SORT 1 8 sorts based on the data within columns 1 through 8 inclusive. SORT 1 15 X sorts all excluded lines based on the data in columns 1 through 15.
