58STOREVAR(EVENT,APPDATA,VAR) ;
59 ;Desc: Allows an app. to store its own application-specific data.
60 ;Input:
61 ; EVENT - ien of event
62 ; APPDATA - variable or array to store **for arrays, pass by reference**
63 ; VAR - **optional** - variable name, may inlucde subscripts.Required if the application needs to store multiple variables or arrays. VAR="APPDATA"is the default
64 ;Output:
65 ; function reuturns 1 on success,0 on failure
66 ;Ex 1
67 ; An app. needs to store a single set of data with the
68 ; event. It could set the data into an array call
69 ; $$STOREVAR(EVENT,.MYARRAY) To get back the
70 ; data it would call $$GETVAR(EVENT,.MYARRAY). (any variable name could have been used instead of MYARRAY.
71 ;Ex 2
72 ; An application needs to store multiple sets of data with the
73 ; the event. It could accomplish that by setting the data into
74 ; multiple arrays, say DATA1,DATA2,DATA3,... and calling
75 ; $$STOREVAR(EVENT,.DATA1,"DATA1"), then $$STOREVAR(EVENT,.DATA2,"DATA2"),etc.
76 ; To get back the named datasets the application would call
77 ; $$GETVAR(EVENT,.DATA1,"DATA1"), $$GETVAR(EVENT,.DATA2,"DATA2"),
