The papers are in a collection entitled "Japanese Perspectives in Software
Engineering", edited by Yoshihiro Matsumoto and Yutaka Ohno, published by
Addison Wesley, ISBN 0 201 41629 8.

After checking, I find my acronym was incorrect - it's EASL (equivalent
assembler source lines). Specific numbers mentioned in the papers was (for
1985) 1.6K EASL/month, not including reused code, 3.1K if you include
reused code. The SOftware Engineering text by Schach (ISBN 0 256 08515 3,
Irwin Publishers) cites an expansion factor of 4 for EASL which translates
into about 400 lines of new "high level" code a month.

As I said in my earlier posting, I'm not sure if the other numbers from Japan
we always hear are EASL or actual high level lines of code, but in the
Addison Wesley collection, manyof the authors specify their data in terms
of EASL.
