Has anyone tried ChatGPT for generating qbasic code? It does a pretty great job! Here's a program I asked it to write, I wanted to compare it to a version I wrote myself. It's first try was nearly identical to what I wrote! I asked it a couple times to try again or make changes, and it kept updating the code as I asked. No idea if this code actually works, I haven't tested it. 100% AI-generated.
Instructions: write a qbasic program that plots a sine wave and exports g-code based on height, distance between waves, and total number of wave variables. It should also draw the shape in screen 12 to a scale automatically determined by available screen space.
Response:
' Program to plot a sine wave and export G-Code
' Declare variables
DIM height AS SINGLE ' Height of sine wave
DIM distance AS SINGLE ' Distance between waves
DIM numWaves AS INTEGER ' Number of waves
DIM maxX AS INTEGER ' Maximum x value (used for scaling)
DIM maxY AS INTEGER ' Maximum y value (used for scaling)
DIM scale AS SINGLE ' Scale factor for x and y axes
' Prompt user for input
PRINT "Enter the height of the sine wave: ";
INPUT height
PRINT "Enter the distance between waves: ";
INPUT distance
PRINT "Enter the total number of waves: ";
INPUT numWaves
' Calculate maximum x and y values
maxX = numWaves * distance
maxY = height
' Set screen mode to SCREEN 12 (graphics mode)
SCREEN 12
' Set scale factor based on screen size
scale = SCREENWIDTH / maxX
' Open output file for writing
OPEN "output.gcode" FOR OUTPUT AS #1
' Loop through each wave and plot the sine function
FOR wave = 1 TO numWaves
FOR angle = 0 TO 360 STEP 1
x = wave * distance + distance * SIN(angle)
y = height * SIN(angle)
' Plot line on screen
LINE (x * scale, y * scale)-(x * scale, y * scale), 15
' Write G-Code command to output file
PRINT #1, "G1 X" & x & " Y" & y
NEXT angle
PRINT #1, "G1 Y0" ' Move back to starting position
NEXT wave
' Close output file
CLOSE #1
PRINT "G-Code generated successfully and saved to 'output.gcode'!"
' Wait for user to press a key before exiting
SLEEP
END

Not going to make up for a lack of programming knowledge, but I can see this generating some very useful chunks of code!

The only bug free code is code that is no longer used.

I've been playing with ChatGPT and I'll share that it does seem to do a good job of "faking it until you make it"; but with that said the results are pretty lacking in my experience thus far. Don't get me wrong, it certainly provides some possible hints and the fact that you can converse with it where it takes the whole of the conversation into consideration... the generated code leaves a lot to be desired. It's possible that my questions are more of the *advanced* in nature... but I have yet to get it give me any code that can simply be used as is (or, for that matter, compile). Will this improve? Maybe. Is it useful... absolutely! If nothing else, it's been valuable in my early experimentation in providing some **hints** of where to go investigate further.
For some real fun... ask it to convert a chunk of ASM code to QB64. ;-)

Mobile app development solutions are designed to help organizations create mobile apps that are tailored to their specific needs. Solutions typically include software development kits (SDKs) that enable organizations to quickly build and deploy mobile apps for multiple platforms. They also include cloud-based tools that allow teams to collaborate on app development projects. Additionally, mobile app development solutions may include analytics tools to help organizations gain insights into user behavior and improve their mobile apps.

Here's my fix:
_Title "b+ once again tries to fix a ChatGPT"
' Dear ChatGPT it's just a sin wave scaleed to screen in the display
' God only knows what a G-Code file is but I can guess from what was
' being output?
' qbasicdude it doesn't work and takes a fair amount of fixing
' Program to plot a sine wave and export G-Code
' Declare variables
Dim height As Single ' Height of sine wave
Dim distance As Single ' Distance between waves
Dim numWaves As Integer ' Number of waves
Dim maxX As Integer ' Maximum x value (used for scaling)
Dim maxY As Integer ' Maximum y value (used for scaling)
Dim xscale As Single ' Scale factor for x and y axes
Dim yscale As Single ' need 2 scales to fit inside screen and fill most of the screen
' Prompt user for input
Print "Enter the height of the sine wave: ";
Input height
'height = 100 'while fixing lets not answer over and over
Print "Enter the distance between waves: ";
Input distance
'distance = 200 'while fixing lets not answer over and over
Print "Enter the total number of waves: ";
Input numWaves
'numWaves = 3 'while fixing lets not answer over and over
' Calculate maximum x and y values b+ over sizes the screen to put graph inside it
maxX = numWaves * distance + 4 ' plus some to draw inside screen
maxY = 2 * height + 4
' Set screen mode to SCREEN 12 (graphics mode)
Screen 12
' Set scale factor based on screen size
xscale = _Width / maxX
yscale = _Height / maxY
' Open output file for writing
Open "output.gcode" For Output As #1
' screen orientation
Line (x * xscale + 1, 0)-(x * xscale + 1, _Height), 15 ' mark start wave
Line (0, height * yscale + 3)-(_Width, height * yscale + 3), 15 ' mark x axis
' Loop through each wave and plot the sine function
For wave = 1 To numWaves
Print #1, ""
Print #1, "G1 Wave:"; wave ' label wave number and repeat wave times
Print #1, "G1 Y0"; height ' Move back to starting position
For angle = 0 To 360 Step 1
' calc: consider each angle a step of 1 across x axis 360 steps per wave with distance = distance
x = (wave - 1) * distance + angle / 360 * distance
' so x = completed waves * distance + angle * scaling of distance or (angle/360) * distance
y = height + height * Sin(_D2R(angle)) ' sin function needs radian units ChatGPT always misses this!
' so y = midscreen +/- some fraction of height according to sin of angle
' Plot line on screen need the scale factors here
Circle (x * xscale + 1, y * yscale + 3), 1, 15 ' +1 +3 again to keep entire graph on screen
' Write G-Code command to output file
Print #1, "G1 X"; x; " Y"; y
Next angle
Line (x * xscale, 0)-(x * xscale + 1, _Height), 15, BF ' mark the end of another period or wave
Next wave
' Close output file
Close #1
Locate 14, 10: Print "G-Code generated successfully and saved to 'output.gcode'! zzz..." ' < zzz... sleeping
' Wait for user to press a key before exiting
Sleep
End

Oh G Code is for running machines, like telling them where to go, OK then probably didn't need my wave number label. Do they take commented lines?

(I am new, I don't know if I'm allowed to post straight Internet link.)
Ask chat to produce code to load font or image or music file. Maybe have to say "on Linux" so it doesn't give Windows path.
I wanted that topic to go on much longer.
