Parameter name colons are enabled and therefore required

  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:  Add colons to your parameter declarations and
  references.
