maximum characters per row in textarea

[ckwall]

Can I make it so that each row has a maximum character limit?
If so how?
Can I make it so that if the limit is reached, it will start a new line?

<FORM NAME="fa" ACTION="today_in_lex.php" METHOD="POST">
<br><B>Today in Lex:</B><br>
<TEXTAREA NAME="Today_in_Lex" ROWS=5 COLS=40></TEXTAREA>
<INPUT TYPE="submit" VALUE="Update">
</FORM>
