Perhaps my English is not so clear; let's try again.

Fast string routines exist right now in REALbasic.

Consider this code. Of the two loops, which would you expect to be faster?

  const kReps = 1000000

  dim t1, t2 as double

  t1 = microseconds
  for i as integer = 1 to kReps
    dim s as string = "something"
    s = s + " "
    s = s + "else"
  next
  t1 = microseconds - t1

  t2 = microseconds
  for i as integer = 1 to kReps
    static output( 2 ) as string
    output = array( "something", " ", "else" )
    dim s as string = join( output, "" )
  next
  t2 = microseconds - t2

  t1 = t1 / 1000000
  t2 = t2 / 1000000

dim tally as string = format( t1, "#,0.000" ) + chr( 13 ) + format ( t2,
"#,0.000" )
  MsgBox tally

If you said the second, you would be wrong. The first ran almost twice as
fast as the second. Even replacing the second loop thusly to avoid the
creation of the array each time does not make it faster than the first:

Okay.  Were you intending this to be a counterexample to my claim?
