OPEN_OVER #channel, device_filename or

OPEN_OVER#channel, [device_]filename(Toolkit II only)


Toolkit II, THOR XVI

This command is exactly the same as the Toolkit II version of OPEN_NEW except that if the specified filename already exists, the filename is automatically overwritten. Also, the THOR XVI version of this command does not support the default data device.


See OPEN_NEW! The Minerva variant of OPEN, OPEN_IN and OPEN_NEW can all be made to work in the same way as OPEN_OVER. FOP_OVER is a function which operates like OPEN_OVER except that it allows any errors to be trapped.
