Hi,
I made a text console to display values and messages. I use it to debug my programs. You have only to copy/paste the code to use it with the new functions (cout, coutln, ... see sample). It’s a shared program (so let’s be friend). I have posted my code on the forum (in the thread ‘who am I’).
Regards,

@pico8-jihem You can put the friend code in the signature as well, so it will easily be accessed whenever you post about shared projects.

Done :-)
Thanks a lot @Nisse5, I haven't seen this feature on my profil before...

@poof92 Here's some code. I put some comments in, to document what's going on.

// This function displays text in a box, one line at a time
function DisplayTextBox(textarray)
   // Wait until A button is up
   while controls(0).a loop repeat
   // Calculate how many lines the text is
   textrowcount = len(textarray)
   // Process one line at a time
   for i = 0 to textrowcount loop
      // Draw a black box to the screen buffer (box is 150 pixels high)
      box(100,500, 700, 150, black, false)
      // Draw a single row of text in white to the screen buffer (text is 50 pixels high)
      drawText(120, 520, 50, white, textarray[i])
      // Draw instruction text in white and with a smaller text size
      drawText(120, 600, 30, white, "Press A")
      // Display the screen buffer content on the screen
      update()
      // Wait for A button to be pressed down
      while !controls(0).a loop repeat 
      // Wait until A button is up
      while controls(0).a loop repeat
   repeat
return void

text = [
"First line",
"Second line"
]

// Main loop
loop
    clear(green)
    print("Press A to display text box")
    c = controls
    if c.a then
       DisplayTextBox(text)
    endif
    update()
repeat

@poof92 I also shared the sample code now (as "Text Box Sample").
