Method 2: Retrieve the next terminal whose table has a sequence of
matching bytes.
This method compares the contents of the physical terminal tables
within a group, and locates the one that matches a byte sequence. In
addition to the data buffer, table location and number of bytes to be
compared, the caller also specifies a terminal ZLU within the group to be
searched.
In order to make it easier to handle multiple matches in a group, the
search starts from the next terminal following the specified ZLU. Hence,
a returned terminal ZLU may be used in the next ptfind call to locate the
next matching terminal. In this case, the whole group is searched if a
terminal is returned the second time.
