Sub or Function statements are similar methods, without distinction. They receive parameters by reference allowing them to be modified. LibreOffice Basic compiler accepts their respective syntax to be used interchangeably.
[Private | Public] Sub name[(argument1 [As typename][, argument2[char][,...]])]
' statements
[Exit Sub]
' statements
End Sub
name: Name of the subroutine.
arguments: Optional parameters that you want to pass to the subroutine.
argument fragment
{[Optional [ByRef|ByVal]]|ParamArray} argument {{As typename|char}[ = expression]|[()]As Variant}
Parameters
Optional: The argument is not mandatory.
ByRef: The argument is passed by reference. ByRef is the default.
ByVal: The argument is passed by value. Its value can be modified by the called routine.
char: Type declaration character.
typename: Primitive data type name. Library or module defined types can also be specified.
= expression: Specify a default value for the argument, matching its declared type. Optional is necessary for each argument specifying a default value.
ParamArray: Use ParamArray when the number of parameters is undetermined. A typical scenario is that of a Calc user-defined function. Using ParamArray should be limited to the last argument of a routine.
UsingParamArray or = expression require Option Compatible to be placed before the executable program code in a module.
When using Option VBASupport 1, Optional arguments with no default value (= expression) are initialized according to their data type, except if Variant.
