Release Notes--V1.3

• An option now exists to allow the same NDF to be used both as input and output for a command, in which case the original contents of the NDF will be over-written by the output of th ecommand when the command terminates. This option is disabled by default so that past behaviour is unchanged (i.e. an error is reported if the same NDF is specified as both input and output). To enable this facility define the environment variable KAPPA_REPLACE, giving it any arbitrary value.

• A bug has been fixed in ZAPLIN which caused looping to occur in interface mode even if the LINCOL parameter was specified on the command line.
