whats up

Language: BASIC

In BASIC, the "WHAT'S UP" command is not a valid command. However, if you're looking for a way to greet or ask how someone is doing in BASIC, you can use the PRINT statement to display a message. For example:

10 PRINT "Hello! How are you?"
20 INPUT "Please enter your response: ", response$
30 PRINT "You said: " + response$

This code will display the message "Hello! How are you?" and then prompt the user to enter their response. The response will be stored in the variable response$, and it will be displayed back to the user.

Please note that the above code is a simple example and can be customized based on your specific requirements. Let me know if you need further assistance!
