Location Base

Specifies the base for both the address and length fields. Data can be entered in either decimal or hexadecimal.

Count

Defines the count or repetition for this bookmark. The default value is 1, however, you can define a repetition (or array) of bookmarks. The location address and location length is used for the first bookmark, however, the Count Sequential Address and Count Fixed Length parameters define how addresses and lengths are calculated for subsequent bookmarks.

Count Sequential Address

Determines whether array bookmarks begin immediately after the end of the last array bookmark or if the location address is re-evaluated for each bookmark. The default is checked (or true), however, one may want to change this if the address is based on a calculation.

Count Fixed Length

Determines whether array bookmarks should use the length of the first bookmark or if the length should be recalculated each time. The default is checked (or true), however, one may want to change this if the address is based on a calculation.

Interpret Data As Type

Identifies the data type for this bookmark. The bookmark results window will display the document data rendered as this type. Additionally, within the bookmarks results window, you can edit the bookmark in its native interpretable data type.

Interpret Data As Byte Order

Identifies the byte order for this bookmark. This parameter is only valid if a interpretable data type is selected.

Interpret Data As Structure
