## Field Description

The following table lists the fields in the Log Viewer panel:

Field | Description
--- | ---
ISPF Log | You can specify a log to view by specifying the values for Project, Group, and Type; or a fully qualified cluster name in the Other VSAM Cluster Name field. If this field is blank, the value of the Other VSAM Cluster Name field is used.
Display Format | The format to display entries. The valid values are 1 and 2. 1: one recorded entry per line (truncated when necessary). 2: a two-line display where the description is on the second line.
Direction | The direction of reading entries. The Backward direction starts with the most recently recorded entries and reads backward for the specified number of records, thus showing the most current activity. Valid values: Forward and Backward.
Number to Read | The number of recorded entries to display. If you do not specify a value, a default value of 200 is used.
VSAM Debug | The debugging level for the VSAM access routines. Do not change this value unless requested by TIBCO Support. The default value is zero (0).
Pgm Debug | The debugging level for the ISPF interface program. Do not change this value unless requested by TIBCO Support. The default value is zero (0).
