Open a Data Set or Member

You can open files by right-clicking on the file in the Director List view. You can also open files that are not listed in your Directory List view by selecting a server and then selecting Open from the CA File Master Plus menu.

Follow these steps:

1. Open the Directory List view.
2. Right-click the data set or member that you want to edit and select Open.

   The Open Data Set wizard opens.

3. Complete the following fields, or verify that the prefilled information is correct:

   Data set name

   Specifies the name of the data set that you want to open.

   Member name

   Specifies the name of the member that you want to open.

   Note: This field is only active when the data set is partitioned.

   Volume serial

   Enter the volume serial only if the data set is not cataloged. Otherwise, leave this field empty.

4. Specify Edit as the Open mode.
5. (Optional) Modify the values in the Change log options. These values are prefilled with the values you specified in the Configure Mainframe Settings dialog. The Change log options are activated when the Enable change log option is selected.

   Note: Select this only when directing the change log to a specific volume.

   Primary allocation

   Defines the number of cylinders to indicate the space of the primary allocation of the change log data set. The value must be greater than zero.

   Secondary allocation

   Defines the number of cylinders to indicate the space of the secondary allocation of the change log data set.

   To switch to another display mode once the editor is open, right-click anywhere in the editor and select a display format from the menu. Once the file opens, you can switch between Character and Hexadecimal format by clicking on the icon at the top of the file view.

8. Specify a layout. Do one of the following.
   • Select from the drop-down list a layout displayed in your Layout view.
   • Specify the layout data set and member name.
