File Information Setup
The <mentry>DO^DIC1</mentry> entry point retrieves a file's file header node, code to execute its identifiers and its screen (if any), and puts them into local variables for use during lookup into a file.
If $DATA(DO) is greater than zero, <mentry>DO^DIC1</mentry>x will QUIT immediately. If DIC("W") is defined before calling <mentry>DO^DIC1</mentry>, it will not be changed.
