Selecting records to browse

Browse - Dataset Specification screen. Using a pattern data set name.

image2021-6-15_10-40-42.png

Use the Browse - Dataset Specification screen to define your browse request, which consists of:

  • Browse Mode
  • Browse Dataset
  • Record Layout and XREF Information
  • Selection Criteria Usage Information.

In this exercise, you create temporary selection criteria to view a subset of records. You supply a record layout to view the data in formatted and vertical formatted display modes.

Steps:

  1. Type an F in the Browse Mode field to request the Formatted mode for viewing your data records.

  2. Type the data set name and pattern character FASAMP.* in the Dataset name or zFS path field.

    The asterisk is a pattern character. It represents any single-level qualifier, or partial-level qualifier when it is preceded by 1 to 7 characters. When you use a pattern character in a data set name, File-AID displays a list of data set names that match the pattern you specified. You can then use the S line command to select a data set from this list. Other valid pattern characters include question mark (?) and percent (%) (single character), as well as plus (+) and slash (/). For more information on pattern data set names, see Getting-started-with-BMC-Compuware-File-AID-MVS-online-options.

  3. Type an S in the Record layout usage field to indicate that you are using a single layout member to describe your data records.

  4. Type the data set name FASAMP.LAYOUTS in the Record layout dataset field.

    The record layout dataset is a data set containing the source code for one or more record layouts. You can use a layout that is embedded in a source program. An XREF member is used to extract an embedded layout from a source member. A record layout dataset can be a sequential, partitioned, PANVALET, or LIBRARIAN data set. File-AID Release 6 map libraries are fully supported. The record layout must be a valid COBOL or PL/I declaration. Otherwise, the displayed data may be invalid.

    Specifying a Concatenation List

    To specify a concatenation list to be used in place of the Record Layout dataset, enter a plus sign followed by the member name (+membername) of the member containing the list. Enter this in the Record layout dataset field instead of the Record Layout dataset name. For example, if the member RLPROD contains the list to be used, enter +RLPROD instead of a Record Layout Dataset name. You specified the name of the concatenation list data set in Option 0.1, File-AID system parameters (see “Concatenation List DSN” of the System-Parameters). The concatenation list data set contains members known as concatenation lists. Each such list contains names of record layout data sets, each of which in turn contains record layout members.

    The concatenation list is used in place of the single Record Layout dataset name. If the concatenated libraries contain duplicate member names, File-AID will always select the first occurrence of the member name.

  5. Type the member name EMPLOYEE in the layout Member name field.

    If you do not specify a member, File-AID displays a list of members. You can then select a member from this list.

  6. Type a T in the Selection criteria usage field to indicate that you want to create a new temporary selection criteria specification.
    Selection criteria enables you to select specific records in a data file for processing. Usage option T (Temporary) dynamically invokes the Selection Criteria function and presents the Selection Criteria Menu.

    When you specify either T or Q in the Selection criteria usage field on the Browse - Dataset Specification screen, File-AID permits you to save your temporary selection criteria by issuing the SAVE command. File-AID displays a screen to give you the opportunity to save your criteria permanently in a selection criteria data set. Your sample training file, userid.FASAMP.SELCRIT, may be used to save selection criteria you create.

  7. Press Enter. File-AID displays the Dataset List illustrated in Selecting From a List of Data sets Matching Your Pattern. Catalog Utility Dataset List Screen.
