 ;
STOREVAR(EVENT,APPDATA,VAR) ;
 ;Desc:  Allows an app. to store its own application-specific data.
 ;Input:
 ;   EVENT - ien of event
 ;   APPDATA - variable or array to store **for arrays, pass by reference**
 ;   VAR - **optional** - variable name, may inlucde subscripts.Required if the application needs to store multiple variables or arrays. VAR="APPDATA"is the default
 ;Output:
 ;  function reuturns 1 on success,0 on failure
 ;Ex 1
 ;  An app. needs to store a single set of data with the
 ;  event.  It could set the data into an array call
 ;  $$STOREVAR(EVENT,.MYARRAY) To get back the
 ;       data it would call $$GETVAR(EVENT,.MYARRAY).  (any variable name could have been used instead of MYARRAY.
 ;Ex 2
 ;  An application needs to store multiple sets of data with the
 ;  the event. It could accomplish that by setting the data into
 ;  multiple arrays, say DATA1,DATA2,DATA3,... and calling
 ;  $$STOREVAR(EVENT,.DATA1,"DATA1"), then $$STOREVAR(EVENT,.DATA2,"DATA2"),etc.
 ;  To get back the named datasets the application would call
 ;  $$GETVAR(EVENT,.DATA1,"DATA1"), $$GETVAR(EVENT,.DATA2,"DATA2"),
 ;  etc.

 ;  HL7MSGID - **optional** - if the event pertains to a specific message, this should be passed
 ;  SITE - **optional** - the station number, including any suffix, where the event occured. Will assume the local site if not passed in.
