	That makes sense. I can see two ways of concatenating that are
similar, but the one approach would seem obviously faster than the other:

strOutput = "Some static text and " & _
   someVariable & " some more text, " & _
   "and yet " & anotherVariable & _
   " still some more text that could go on forever."

would seem faster than

strOutput = "Some static text and "
strOutput = strOutput & someVariable & " some more text, "
strOutput = strOutput & "and yet " & anotherVariable
strOutput = strOutput & " still some more text that could go on forever."

	(Caveat: I haven't actually tested one approach against the other to
see which is faster.)
	But if you are iterating through a database recordset, for example,
where you could either concatenate an ever-growing string of database
results, or Response.Write the data after each loop through the recordset,
the Response.Write approach would almost certainly be significantly faster,
especially with a large recordset. Right?
