(j3.2006) (SC22WG5.4200) Web about IBM 1401 Fortran

[Van Snyder]

Ed Thelen <ed at ed-thelen.org> has prepared a web page about IBM 1401
Fortran II at
http://www.ed-thelen.org/1401Project/1401-FORTRAN-Illustrated.html.  In
it, he describes each of the 63 phases of the compiler, interleaved with
the code for the phase.  These descriptions are from the IBM Systems
Journal paper referenced below, and are complementary to the
descriptions in the IBM manual
http://www.bitsavers.org/pdf/ibm/140x/C24-1455-2_Fortran_Specifications_and_Operating_Procedures_Apr65.pdf

The phase listings are the ones I prepared by disassembling and reverse
engineering an operational tape.  I did this because the primary author,
Gary Mokotoff <mokotoff at earthlink.net>, told me his listing had
accidentally been discarded when he retired.  A few years later he found
it and sent me a copy.  I transcribed and assembled it, and compared the
results to the operational tape, to "proofread" it.  There might still
be typos in the comments.  Ed doesn't provide that code on his web.

Paul McJones <paul at mcjones.org> believes the IBM Systems Journal paper
(v.4, no.1, 1965, pp 73-80) ought to be required reading in computer
science curricula.  There is an online scan of the paper at 
http://www.research.ibm.com/journal/sj/041/ibmsjIVRIH.pdf but page 78 is
missing.  Randy Neff <randall.neff at gmail.com> and Robert Garner
<us032560 at mindspring.com> sent Ed the missing page.  An OCR version,
including the missing page, is available at
http://ed-thelen.org/1401Project/1401-IBM-Systems-Journal-FORTRAN.html

If anybody wants the source code files I'm happy to send them.
