FileOpActionclass
A base class for file-oriented actions, such as SCRIPT, RECORD, and REPLAY. We provide common handling that prompts interactively for a filename; subclasses must override a few methods and properties to carry out the specific subclassed operation on the file.
DefineSystemAction(FileOp) // original source text
class FileOpAction : SystemAction// after macro expansion

Methods
execSystemAction ( )OVERRIDDEN
Each concrete action subclass must override this to carry out our operation. This is called when the user has successfully selected a filename for the operation.
performFileOp (fname, ack, desc, :?)
Carry out our file operation.
‘desc’ is an optional named argument giving a description string entered by the user via the Save Game dialog. Some versions of the Save Game dialog let the user enter this additional information, which can be stored as part of the saved game metadata.
setUpFileOp (ack)
ask for a file, and carry out our operation is we get one
