You cannot use Switch as a variable name since this is a
built-in function. And it seems to me the built-in function does
what you are describing without use of a goto operation.
That is:
Switch[x,
1, (code segment 1),
2, (code segment 2)]
will run code segment 1 if x is one and code segment 2 if is 2.
The code segments can be any number of function calls
expressions joined with a semicolon that forms a Mathematica
compound expression. Look at the documentation for Switch.
