Function and procedure
declaration
Procedure declaration without argument :
Procedure ProcedureName :
'...instructions
|
You haven't to set the end of the procedure. The
compiler will take the end of the procedure as the
end of or the beginning of the next Module.
Procedure declaration with argument :
Procedure ProcedureName: (Arg1 as TypeArg1, Arg2 as TypeArg2, ...)
'...instructions |
Example :
Procedure Hello : (a as Integer, b as Long)
'...instructions
|
Function declaration:
A function is a procedure which returns a value.
It can be called in an expression.
Function FunctionName: (Arg1 as TypeArg1, Arg2 as TypeArg2, ...) as TypeReturnedValue
'...instructions
|
To return the value, you must use the specific
Return
keyword.
For example, a function that returns twice the
integer given :
Function fTwice: (a as Integer) as Integer
Return a*2
|
Note : The colon (":") after the name of the function are not needed.
After, we will be able to use this function in an expression.
Procedure Hello :
'...
b = 2*4+fTwice(6)
'...
|
Here, b is 2*4+12 = 20
If you want to declare a function without argument, the syntax is :
Function FunctionName:() as TypeReturneValue
