Absolutely true, and that led to one of the more famous computing screw-ups
in the early space program. The author intended to write this:
DO 10 I=1,8
which, in Fortran, begins a loop that will run 8 times ending at the
statement labeled "10". In this case, the author mistakenly typed a period
instead of a comma:
DO 10 I=1.8
That, unfortunately, is a perfectly valid statement that assigns the value
"1.8" to the floating point variable "DO10I", supposedly resulting in the
loss of an unmanned launch vehicle...
