There can already be stuff in userdata that you don't want to loose.
OK.
- arguments for the user.data.table function are given as
strings : "
#1" and changed in numbers in the body of the function. I noticed
that
it was possible to
give numbers directly. is there always better to do like this ?
(enter
strings et use tonumber)
Depends on if you want to catch errors. Forgetting an argument (or
an empty one) when a number is expected results in ,, which triggers
a Lua error, while with ,"", you can intercept the empty string and
default.

OK. Thanks !
