I've been writing code form almost 50 years (with a 3 year break flying 
helicopters in Viet Nam). While back in the 60s I just knew Fortran and 
BASIC, but in the 70s when I worked for a large company, some of the 
software we purchased and customized, but there has always been a 
philosophy of design-code-testand evidence that better code was produced 
if it were designedand the design was properly reviewed, and that the 
guys who wrote the code participated and then followed the design. The 
main issue here is to find any problems in the design. Time frame here 
is the late 1970s. Much of my time after that was working with compilers 
and run-time libraries and porting code between architectures.
