    02:31 Outputting data to disk - CSV files
    09:04 Reading data back from disk - CSV files
    10:52 Detecting the end of a file - EOF()
    15:25 Appending data to an existing file
    17:39 Outputting "freer" text to disk - Print statement
    24:15 Reading text back from a disk file - Line Input statement
    26:48 Closing files

    How do you magnify the screen, is that a MAC thing?

  • Wow, QB was doing CSV files from beginning with Write, I probably learned that back in 90's and forgot all about it. Print #fh was alwys my main Output or Append command.

    @FellippeHeitor  Susan Sarandon is 74 so I imagine she would be complimented by your age estimation :)

    Same with Windows.
    Nice video Fellippe.
    Granted after becoming radioactive I only have a half-life!

  • hi, on my Toshiba windows 10 ctrl+wheel of mouse has many different results depending of the situation:
    in the webbrowser it changes the vision zooming in or out
    in a window of system with forlders it cicles among the different ways to see the icons in that window
    on the desktop image it makes a zoom in or out of icons but not  of the image used as background

    but if you go into menu of windows accessories and you activate magnify glass  then you can use  ctrl+ wheel of mouse to magnify
    Programming isn't difficult, only it's  consuming time and coffee
