  Associated File Control Blocks ❷

*** Bottom of data.

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.
