“Write an AppleSoft Basic program to do the computation”
(Here it gives me a simplistic Basic program that wouldn’t work because the number would be too large)
Me: “AppleSoft Basic can’t handle numbers that long”
ChatGPT:
You're correct that the integer arithmetic in AppleSoft BASIC has some limitations and cannot handle numbers as large as the sum of the two numbers you provided. AppleSoft BASIC is a 16-bit programming language, which means that it can handle integer values from -32,768 to 32,767.
If you want to work with very large numbers in AppleSoft BASIC, you can use a string to store the numbers and write your own code to perform arithmetic operations on the strings. Here's an example program that demonstrates this approach:
10 A$ = "12348120348102341"
20 B$ = "10823401828482"
30 L = LEN(A$)
40 M = LEN(B$)
50 IF L < M THEN A$ = LEFT$("0", M - L) + A$ : L = M
60 IF M < L THEN B$ = LEFT$("0", L - M) + B$ : M = L
70 C$ = ""
80 R = 0
90 FOR I = L TO 1 STEP -1
100 D = ASC(MID$(A$, I, 1)) + ASC(MID$(B$, I, 1)) - 96 + R
110 C$ = CHR$(D MOD 10 + 48) + C$
120 R = INT(D / 10)
130 NEXT I
140 IF R > 0 THEN C$ = CHR$(R + 48) + C$
150 PRINT C$
