Final answer:
A QBASIC program for printing the first 20 natural numbers using a goto statement involves initializing a counter, printing the counter, incrementing it, and using the goto statement to loop until the counter exceeds twenty.
Step-by-step explanation:
In QBASIC, a simple program to print the first 20 natural numbers using a goto statement can be written as follows:
DIM i AS INTEGER
i = 1
LABEL1:
IF i > 20 THEN GOTO ENDPRINT
PRINT i
i = i + 1
GOTO LABEL1
ENDPRINT:
END
This is a basic QBASIC program loop which uses the goto statement to repeatedly print natural numbers. The variable 'i' starts at 1, and after each print operation, it is incremented by 1. The 'LABEL1' serves as a target for the goto command to loop back to continue the printing process. Once 'i' becomes greater than 20, the program skips to the 'ENDPRINT' label, which leads to the end of the program.
