What happens if the 'on start' block is replaced with the 'forever' block?The number '7'

In a coding context, the 'on start' block and the 'forever' block have different functions.

1. The 'on start' block is used to initiate a program or a set of instructions. Whatever code you put inside this block will run once when the program starts.

2. The 'forever' block, on the other hand, is used to continuously run a set of instructions. Whatever code you put inside this block will run indefinitely until the program is stopped.

So, if you replace the 'on start' block with the 'forever' block, the code inside the block will run continuously instead of just once at the start of the program.

The number '7' in your question seems to be out of context. If it's part of the code inside the 'on start' block, replacing it with the 'forever' block will cause the action associated with '7' to be executed indefinitely.
