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 InputFile 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
