Primary option: Open Files

Selecting the "Open Files" option provides you with a display that lists all open files which could not be associated with any particular event, as well as files that might be listed in the detail section of the report for individual events. An example of the open file list is shown in Figure 1.

If the data set shown at ❶ is QSAM, VSAM, or IAM, and exists, then it is presented as a point-and-shoot field, that if selected, shows a selection menu from where either Edit, View or Browse can be chosen. If Z Data Tools is available, then it is used to perform the requested function against the data set. Otherwise, if the data set is QSAM non-spanned record format, then ISPF is invoked.

For more information about the presentation of open file buffers, see Open file record information.

An "Associated File Control Blocks" point-and-shoot field might be available at the bottom of the File Information display, as shown at ❷ above. By placing the cursor on this field and pressing Enter, the Associated File Control Blocks display is presented. An example of this display is shown in Figure 3.
