First, I would change your "goto"'s to "gosub"'s. Your question I really don't understand...sorry

Um, I'm not completely sure, but shouldn't you have quotes "" around your operands?

Eg.


Can you try that and see if it helps?

Tinkergirl is onto the problem!

You have:

Input "Enter Operand, + Addition, - Subtraction, / Division, * Multiplication ", operand#

operand# is a float variable for storing real numbers - like 1.234 or 43.663.

You want to enter alphanumeric characters, so you need to be using a string for the input, (strings have a $ sign on the end of the variable name). So, it should be:

Input "Enter Operand, + Addition, - Subtraction, / Division, * Multiplication ", operand$

Then , Tinkergirl is correct - you should have quotes around the signs, as in:

if operand# = "+" then GOSUB add

masterprogrammer is also correct. Stop using Goto and use Gosub instead. Goto is the gateway to spaghetti code and your programs will be a nightmare to follow. Instead, use Gosub and use:

add:
print "The Sum Of ", num1#, " And ", num2#, " Is ", num1# + num2#
wait 3000
Return

Do the same to the other blocks too.
