vbCrLf in VB[Script]. Assuming you're using VBScript with ASP, then you
could (for example) substitute html tags for line breaks thus:

sText = Request.Form("Text")
sText = Replace(sText, vbCrLf, "<br />")

Or:

sText = Replace(sText, vbCrLf & vbCrLf, "</p>" & vbCrLf & "<p>")
sText = Replace(sText, vbCrLf, "<br />" & vbCrLf)
sText = "<p>" & vbCrLf & sText & vbCrLf & "</p>" & vbCrLf
