Syntax
Public SUB <name> ({ {ByVal} <p_1> as <type_1>}…{, {ByVal} <p_n> as <type_n>})
{ local variable declaration }
{ subroutine code }
END SUB

Type
Parmeters: Long, Double, String, Joint, Location, user defined structures, Generic Axis, Generic Group, Moving Frame (by reference only), Cam (by reference only), Comp (by reference only), Semaphore (by reference only), user defined Error and Note (by reference only).
