I always use CVS comma delimited.
now the code,I want this data, which are contacts info, inside the table of the contacts package.
Here things are more difficult, because my example inserts data into a plain table, while 'contacts' are stored into the content repository and moreover makes use of the 'ams' package to dynamically extend the contact's attributes. You will have to use some package specific proc to load your data, but I can't help you because I never used it.
Where should i post and adapt this script? in a random tcl file, which i created in a random test directory?
Any place where you can point your browser is good.
