==== Usage ====<syntaxhighlight>Arw_GetFirst (Origin)</syntaxhighlight>  Parameters Origin - a numerical expression specifying the origin of the arrow object:

== Parameters ==:'''Origin''' - a numerical expression specifying the origin of the arrow object, where: ::'''1 ''' - added by the current study, ::'''2 ''' - added by a study other then the current study, or drawn manually by the user, ::'''3 ''' - added by any study, or drawn manually by the user, ::'''4 ''' - added by the current study, or drawn manually by the user, ::'''5 ''' - added by a study other then the current study, ::'''6 ''' - added by any study, ::'''7 ''' - added manually by the user.

==== Notes ==== * If the oldest (the first added) arrow object is deleted, the next oldest (the second added) arrow object becomes the oldest (the first added) arrow object. * Use [[Arw_GetActive]] or [[Arw_GetNext]] as another way to get the object-specific ID number of an already created arrow.
