Assigns the specified font size to the text of an arrow object with the specified ID number; . Arw_SetTextSize returns a value of 0 if the font size was successfully assigned, and a value of -2 if the specified object ID number is invalid.

==== Usage ====<syntaxhighlight>Arw_SetTextSize(ObjectID,FontSize)</syntaxhighlight>

Where: [[ObjectID]] - a numerical expression specifying the object ID number

[[:'''ObjectID''' - a numerical expression specifying the object ID number. :'''FontSize]] ''' - a numerical expression specifying the font size .

==== Notes ==== * An object-specific ID number is returned assigned by [[Arw_New]], [[Arw_New_s]], [[Arw_New_self]] or [[Arw_New_self_s]] when the arrow object is created.* Use [[Arw_GetActive]], [[Arw_GetFirst]] or [[Arw_GetNext]] to get the object-specific ID number of an already created arrow.

==== Example ====

<syntaxhighlight>Value1=Arw_SetTextSize(3,16);</syntaxhighlight>
