'init' <internal parameters>
This command defines the window and model size, the model position, rotational center, fonts and others. It is created and written to a file by the “send” command. If that command should change the window dimensions and is used in a batch file, it has to be used in the first line. Otherwhise the window dimensions take only effect after the batch file was completely parsed and executed. A batch file could look like that::
  read init.fbl
  read ccx.frd new
  ds 1 e 1
  plot fv all
  hcpy png
If the window size is not affected by the command then it is not necessarily the first command in the batch file.
