TISERV begins retrieval and sets SCAN-FOLDER-BY-KEY fields to values that
correspond to the item being scanned. Table 2-22 lists the values that TISERV sets as it
progresses through the folder.

The values returned for the fifth item (TERM245) are the appropriate settings for a
subsequent scan of the same folder.
Next,TISERV sets NUM-RETURNED to 5 and outputs the entries in Table 2-23 to the
ITEMS-RETURNED structure. Note that an asterisk (*) is used as a pad character.

Since MAX-KEY-LEN was set to 6, the ordering key values for keys longer than six
characters were truncated to six characters.
