function and sub declaration
Declaration of functions nd subs are similar to basic. In functions to return function values, use implicited declared variable which has the same name of the function. Parameters by reference can also be used, using BYREF directive.
Some examples:
SUB HelloWord
(**Some code here**)
END SUB
SUB UpcaseMessage(Msg)
(**Some code here**)
END SUB
FUNCTION TodayAsString
TodayAsString = DateToStr(Date)
END FUNCTION
FUNCTION Max(A,B)
IF A>B THEN
MAX = A
ELSE
MAX = B
END IF
END FUNCTION
SUB SwapValues(BYREF A, B)
DIM TEMP
TEMP = A
A = B
B = TEMP
END SUB
