Parameter name colons are disabled and therefore illegal

  Explanation:  When the /ANSI_PARAMETERS qualifier is used, the
  module processor requires that all parameter declarations and
  references be prefixed by colons.  When the /NOANSI_PARAMETERS
  qualifier is used (it is the default), the colon prefix is not
  allowed.

  User Action:  Remove colons from your parameter declarations and
  references.
