I am a student in Computer Science in the University of Evry (France),
and I tried to compile a simple ocaml program :
let rec fact = function
0 -> 1 | n-> n*(fact(n-1));;
Unfortunately, the "ocamlopt 1fact.ml" command gave me the following
answer :
/tmp/camlasm29.s: Assembler messages:

I think this is due to the name of the program, 1fact.ml, which should
not begin with a number, because when I renamed the file fact1.ml it
worked perfectly.
Is it normal?
Thank you.
Sarah Djebali.

Correct. The name of a Caml compilation unit is derived from its
source file name (e.g. fact1.ml --> Fact), and must be a valid Caml
identifier.

Well, it could be argued that the compiler should check the file names
and emit a more descriptive error than the one you obtained. But
since you understood the problem perfectly well and found the fix
yourself... :-)

Typo here fact1.ml --> Fact1, and NOT Fact.
