Each record in the file holds an IMAGE entry that qualified from a FIND or MULTIFIND retrieval. The number of records in the file is the same as the number of entries retrieved and the size of each record is the same as the size of the retrieved entry. In a FIND, the records are the size of the entries in a single data set. In a MULTIFIND, the records are the size of the entries in a compound data set.

A compound data set entry is the combined size of the entries in the single data sets of which it is comprised (specified in the JOIN command).

The data in the file is stored in the same form as the data in the IMAGE data base. Numeric data is stored in binary form and must be converted to ASCII before it can be displayed.
