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.
ISPF Line commands
D — To delete the current-line. This short animated-clip demonstrates how to use Insert Line-Command to insert new lines. The next video-snip shows, how lines-of-text can be deletedand removed using the Delete D Line-Command.
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 the data set being processed is on an unmounted file system, a temporary mount is issued, file system. The Command field and the field containing the data set name fields make up a single point-and-shoot field.
If you enter a slash in the Command field or if you select any part of the combined point-and-shoot field, the Data Set List Actions pop-up shown in Figure 1 is displayed so that you can select the command you want to use. Figure 1. Edit View Browse Member List Delete Rename Info Short Info Print Catalog Uncatalog Compress Free SORT sorts data, observing bounds.
The entire record is subject to sorting unless bounds are set.
ISPF COMMANDS – SORT, LOCATE, RESET, FLIP, COMPARE
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.

Note the second field is a single byte. RESET with no operands cleans up everything except line labels. Operands can be provided to specify exactly what to reset:. FLIP swaps excluded and included lines.
Lines existing only in the current file are marked with labels.
Lines existing only in the other file are shown as information lines. Otherwise a DSN or member name is required for the file to be compared to. Other keywords are:.

A Identifies the line after which copied, moved, or model lines are to be inserted. AK Identifies the line after which copied, moved, or model lines are to be inserted, but indicates that another destination of the form A, B, or O is still required proceeding forward through the file before the data is moved or copied to the multiple destinations specified.
B Identifies the line before which copied, moved, or model lines are to be inserted. BK Identifies the line before which copied, moved, or model lines are to be inserted, but indicates that another destination of the form A, B, or O is still required proceeding forward through the file before the data is moved or copied to the multiple destinations specified.
C Copies a line from one location to another. CC Copies a block of lines from one location to another. COLS Displays a position identification line. D Deletes a line. DD Deletes a block of lines. F Redisplays one or more lines at the beginning of a block of excluded lines. I Inserts one or more blank data entry lines. L Redisplays one or more lines at the end of a block of excluded lines.

Line Commands. Line commands that you type in the far left field of a line to perform various actions. You can type multiple commands on different lines before pressing Enter, which processes all commands. Scrolling or any other command that causes the display to change also causes the specified line commands to be processed. The following table is an overview of the Line commands, the corresponding Control Commands, and their function. The following pages provide a more complete description of each command.
Note that some commands have synonyms, such as A. An unconditional "before" breakpoint is set at the specified line. This type of breakpoint stops before. A U remains in the first column to show where breakpoints are set. For assembler, if an A is placed next to a line in the keep window, the access register for that item is displayed.
A conditional breakpoint is set at the specified line. Issuing this command causes the application to display the When screen, where the condition may be specified. The application automatically completes the line number portion of the When screen based on your breakpoint line. The program begins executing Go to the line where the G. The data items on the line where the H. For assembler, the operands for the current instruction in register notation are added to the keep window.
For assembler programs, if an H is placed on a line within the keep window, the high half of the 64bit register is displayed. In instances where a frequency count exceedsInfo displays the actual count at the top right of the screen. For assembler programs, if an I. The data items on the line where the K. Oblank. For assembler, the operands for the current instruction in register notation are written to the session log for later printing.
An RDI, reset data item, is done for each of the data items on the line to remove entries in the keep window.There are 80 character positions on each line of a coding sheet. All character strings must be ended with separators.
A separator is used to separate character strings. A comment is a character string that does not affect the execution of a program. It can be any combination of characters.
A comment line can be written in any column. The compiler does not check a comment line for syntax and treats it for documentation. Comment entries are those that are included in the optional paragraphs of an Identification Division. They are written in Area B and programmers use it for reference. Literal is a constant that is directly hard-coded in a program. In the following example, "Hello World" is a literal.
Alphanumeric Literals are enclosed in quotes or apostrophe. Length can be up to characters. An apostrophe or a quote can be a part of a literal only if it is paired. Starting and ending of the literal should be same, either apostrophe or quote. Length can be up to 18 characters. Sign cannot be the rightmost character. Decimal point should not appear at the end. Length can be up to 30 characters. User-defined words are used for naming files, data, records, paragraph names, and sections.
Alphabets, digits, and hyphens are allowed while forming userdefined words. All the constant values of figurative constants are mentioned in the following table. Previous Page. Next Page. Previous Page Print Page.
