the display. The ability to have multiple threads of execution is very
valuable because it allows a process to continue doing useful work
even though it may also be waiting for another part of the system to
complete a request.
8. "Even though a process is the entity in OS/2 that owns system
resources, the system still needs to keep track of certain things on a per
thread basis" (page 64) including thread ID, stack, processor registers,
dispatch state, and priority.
9. A thread can create and start a new thread that belongs to the same
process using a "DosCreateThread" instruction (pages 67-68).
10. Krantz discloses (page 68):
If multiple threads have the same priority, then OS/2 will
timeslice between the threads. When timeslicing, the operating
system allows each thread to execute a specified amount of time. The
is called round robin scheduling, and it allows multiple threads that
have the same priority to share the processor fairly.
3. Content of Nitta
11. Nitta discloses "a method for automatic translation between natural
languages, and more particularly to a method for automatically translating
English sentences into Japanese sentences" (col. 1, lines 7-10).
12. Nitta is a complex reference, but the main steps of the method are
summarized as follows (col. 3, lines 20-55):
First, an English text is read in and it is written in an input data
buffer storage (text input processing). Next, a lexicon is looked up to
convert words in the text having inflection such as conjugation, plural
inflection and degree inflection to stems (dictionary look-up). Then, a
string of words and idioms in the text is converted to the
corresponding string of parts of speech (part of speech analysis).
Then, the sentence converted to the string of parts of speech is divided
