Why doesn’t the following pseudocode module work as indicated in the comments?

// The readFile method accepts a string containing a filename as // an argument. It reads and displays all the items in the file. Module readFile (String filename) // Declare an input file. Declare Input File file // A variable to hold an item that is read from the file. Declare String item // Open the file using the filename. Open file filename // Read all the items in the file and display them. While eof (file) Read file item Display item End While End Module
