Instead, it called a single assembler-language

specifying which operation to perform, and one
specifying the precision level. That program
used old-style Fortran source, on punched cards
most of the time I was working with that program.
I missed the statement in your reply that you were
referring to a specific program you had worked on.
Sorry about that...
While that is clearly a problem to be dealt with in
updating old code, I still stand by my opinion that
a refactoring program shouldn't be expected to
rewrite that sort of thing...
