#!I50 #!N These routines, used ONLY when the application is connected 
directly to the Data Explorer executive, allow the application to execute 
macros by name. The application can cause the named macro to 
be executed once or to be executed whenever a macro global 
input changes (such as when a value is sent to a 
DXLInput or DXLInputNamed module). The macro may be given a NULL-terminated 
list of arguments (the ...WithArgs form) or a NULL-terminated vector of 
arguments (the ...WithArgsV form). #!I0 #!N #!N #!N #!N #!N  #!F-adobe-times-medium-i-normal--18*
