I am about 1/3rd of the way done with my 800,000 lines of F77 code to 
C++ code.  My custom version of F2C is doing about 60 to 70% of the 
work.  I am equating the task as equivalent to translating about ten 
long engineering books from German to French.  Lots of idioms and basic 
incompatibilities that have to be ironed out.

I was shooting for the end of 2026 but that ship has sailed.  Maybe 
middle of 2027.  Then I have to port to x64 but the port should be easy 
(he says with the ship sitting in ten feet of mud in the harbor).
