I had to debug a FORTRAN 66 program (my own, sadly, written in 1967) that
was going astray in a statement of the form:
IF (X) 101, 102, 103
The problem was that a previous call to a library subroutine, along the
lines of:
CALL SOLVE(A, X, B, 0.0)
was updating the accuracy parameter 0.0 to the residual norm of the solution
(or some such accuracy indication), and this was making the implicit
comparison with 0.0 in the later IF statement go wrong.
