Sperry used to have a balanced tree search that all compilers and assemblers 
used. Very small very fast. Less than 200 lines of code, but used instruction 
modification depending on paths taken. Fairly long intro, but we started 
getting in some large modeling routines from some of the big labs. Well 
balanced tree sort hurled on large programs. Sperry said the code was frozen 
and wouldn't take a fix. WAD. My smart friend David said he could fix it but 
would rewrite in Fortran translating from MIX? Turned out to be almost 300 
lines of Fortran with no instruction modification. Definitely a tad slower but 
would allow the big modeling pgms to compile and run!
