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.
