Text datatype asp mssql 6.5 memo field truncate problem

[John Brown]

Suppose I have a form with a Textarea and some other input fields
I would like to insert the content of the Textarea into a mssql 6.5
text datatype column.
here is the problem, after the insert the datalength() on the newly inserted column reports much less then what was in the textarea. The maxlenght property of the textbox was set to allow 10000 characters
