Function - can return value (but not must) to the calling script
Function with argument and not return value
x = "10"
y = "12"
Call Addition_1(x, y)
Function Addition_1(x, y)
msgbox (x&y)
End Function
Function without argument and not return value
Call Addition_2()
Function Addition_2()
x = "10"
y = "12"
msgbox (x&y)
End Function
Function with argument and return value
x = "10"
y = "12"
z = Addition_1(x, y)
Msgbox z
Function Addition_1(x, y)
Addition_1 = (x&y)
End Function
Function without argument and return value
z = Addition_1()
Msgbox z
Function Addition_1()
x = "10"
y = "12"
Addition_1 = (x&y)
End Function
Subroutine - cannot return value to the calling script
Subroutine with argument and not return value
x = "10"
y = "12"
Call Addition_1(x, y)
Sub Addition_1(x, y)
msgbox (x&y)
End Sub
Subroutine without argument and not return value
Call Addition_2()
Sub Addition_2()
x = "10"
y = "12"
msgbox (x&y)
End Sub
