        "file read"
        SYNTAX: fread
                fread()
                fread n
                fread(n)
                fread(NAME)
                fread(NAME,n)

        Strings may be read from files using the commands "fload", 
        "fopen", "fread", "fclose". (For more information type "?fload",
        "? fopen", and "? fclose".)

        "fread" 
        "fread()"        reads the line the file pointer is pointing to 
                         from the default file ___INP.
        "fread(NAME)"    reads the line the file pointer is pointing to 
                         from the file NAME.
        "fread n" 
        "fread(n)"       reads n lines beginning with the line the file 
                         pointer is pointing to from the default 
                         file ___INP.
        "fread(NAME,n)"  reads n lines beginning with the line the file 
                         pointer is pointing to from the file NAME.
        
        n must be less than 100.
        
        Before reading from a file you must open it using the command
        fopen (see "? fopen).

        "openf" lists all currently opened files.
