       428 bytes allocated in          local_alloc at line   615 of

       428 bytes allocated in          local_alloc at line   615 of

what are these 6256 allocations? why mem not being freed after channel has
gone? Local channel used actively.

  Fix an off-by-one error in the FILE() function, and extend FILE()'s
length parameter to work like variable substitution.
  Previously, FILE() returned one less character than specified, due to
the
  terminating NULL.  Both the offset and length parameters now behave
  identically to the way variable substitution offsets and lengths also
work.
