Define a file processing task that may be run multiple times. Selectively print data records using record layouts, enabling you to tailor the format of the output to meet your specific data requirements.
Change record format by reformatting any type of dataset that is, enlarge data fields, add new data fields. Process datasets selectively to view or update information.
Accumulate totals to verify reports. Read all VSAM and sequential datasets forward or backward. Reformat multiple record type files in one pass. Create a complete subset of related files for testing.
Check control statement syntax online and execute actions in the foreground with File-AID's Interactive utility option 3. Action requests consist of the following: Dataset identification label Name of the function Set of optional selection, action, and control parameters.
This identifier connects an input dataset DD to a function that you want to perform. Function Name Functions identify the action you want to perform on the input dataset.
Most functions can be abbreviated to save keystrokes. Also converts Release 7 saved selection criteria to Release 8 selection criteria format. COPY Copies data selectively or nonselectively. DROP Eliminates unwanted records from a dataset while copying it. DUMP Prints datasets in vertical hexadecimal format. LIST Prints alphanumeric data. USER Performs a copy function that provides greater control over the writing of output records and datasets.
Selection, Action, and Control Parameters Parameters are code words that control or limit processing actions. Parameters define how to select and manipulate records. Parameters are described below, grouped according to type. Call from a program as a subroutine. In this example you practice using the Interactive utility option 3. Performing functions and using logic not available through other utilities. Entering control cards interactively. Viewing results and output at the terminal. Use the 3.
Figure More About the Interactive Utility Screen If you specified the name of a dataset in the "Dataset name" field in the "Optional Control Dataset Information" section, File-AID uses the control statements in the specified dataset to complete your request. The results of execution are immediately shown on the Control Statement screen.
You are not prompted for control statements. File-AID executes the statement and immediately displays any results on the screen. Enter the END command to exit.
Because this is a foreground process, no tutorial information is available for the Control Statement screen. If the warehouse status location 69 is equal to "AVAIL", total the quantity on hand packed field at location File-AID reads the records of the input dataset, tests each record for the condition specified in the control statement, and displays the results as shown in Figure Interactive Utility.
Type BS is also provided to indicate binary signed data for lengths 1, 2, and 3. Location 5 references the first byte of data in the record. In this example, you notice that the RDW parameter is not used. Exiting Interactive Execution Results of your request are displayed immediately at your terminal as shown in Figure When the Steps: Type END. After you have created the JCL once, you can use the same JCL as a model for subsequent runs just by changing control statements and dataset names.
You need to update the JCL for 15, jobs because you upgraded from to disk drives. Statement DD01 defines the input dataset. Statement DD01O defines the output dataset. Comments may be entered on any control statement after one space following a parameter. This example illustrates how you can make a single pass through a master file in this case 34 reels of tape to create two extract output files that contain different subsets of data.
The following control statement determines which programs must be changed to reflect the new company name. Labels: Draft , File-Aid. Newer Post Older Post Home. Powered by Blogger. Follow us. Prints the audit trail file in formatted, character, or hexadecimal format.
Prints alphanumeric data and labels each record with its record number and RBA. Prints the dataset containing selection criteria created from File-AID online functions. Allows selection parameters to be combined with ACCUM parameters to provide audit-type totals for files. Performs a copy function that provides greater control over the writing of output records and datasets.
Displays VTOC summary information and dataset names in alphabetical sequence based on the specified parameters.
Displays volume information and datasets in address location sequence based on the specified parameters. Specifies the processing of records based on their contents. Indicates movement or change of data. Defines basic environment conditions during execution. Places record count limits on the datasets being processed.
Provides a hardcopy report of records being processed.

File AID Tutorial and useful commands
File aid is having two types one which is used for File operations and second one is used for DB2 file aid for DB2. Here we are going to discuss about the file aid for files. For ex: we can browse a file by using its layout, the number of records in a file can be limited according to our requirement By using the selection criteria option. Here we will see some basic options of file aid with examples. U Unformatted and C character formats do not require any input file lay out data sets. Where as other two requires a file layout. C Mode: It looks like the normal file browsing 3.
