Azpierrutina bat definitzen du.


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.

      {[Optional [ByRef|ByVal]]|ParamArray} argument {{As typename|char}[ = expression]|[()]As Variant}

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.
