How do redirect screen and keyboard I/O?
A. This non-standard functionality may be present in a module called InOut or (in an extension to ISO versions) in RedirStdIO. The procedure to use is OpenInput (or OpenOutput). Unfortunately these behave differently in every version (one of the reasons we built a standard). Some versions produce a prompt at runtime, others take a file name. The latter may or may not require a file extension. They may look for the name as you have provided it and if they don’t find it, try with the default extension .txt Others have a way of entering the extension. You will have to consult the documentation.
