49 ;
50 ;$$GETDATA^OCXCACHE(RESULTS,EXTERNAL CALL,PATIENT ID,TIMEOUT) ----> returns either a 1, 2, 3, or 0
51 ; 0 -> No Errors
52 ; 1 -> Missing External Call.
53 ; 2 -> Missing Patient ID.
54 ; 3 -> Cache Data Missing.
55 ;***Results = Data Value Returned,
56 ; Either Scalar or Array.
57 ;
58 ;***External Call = Routine call in a 'resolved parameter' format to
59 ; reduce the chances of cache returning the wrong values.
60 ;
61 ; If ORDFN=1234 and TEST=110 and SPECIMEN=119
62 ;
63 ; Then If this parameter is: "$$LOCL^ORQQLR1("_ORDFN_","_TEST_","_SPECIMEN_")"
64 ; then the value will be stored in subscript: "$$LOCL^ORQQLR1(1234,110,119)"
65 ;
66 ; If this parameter is: "$$LOCL^ORQQLR1(ORDFN,TEST,SPECIMEN)"
67 ; then the value will be stored in subscript: "$$LOCL^ORQQLR1(ORDFN,TEST,SPECIMEN)"
68 ;
69 ;***Object ID = If this is patient data then this will be the patient's DFN.
70 ; If this is user data then this will be the user's DUZ.
71 ; etc...
72 ;
73 ;***Timeout = (Optional Default = 300 (5 Minutes)) How long, in seconds, the data has to live in the cache.

76 ;
77 ;^XTMP("OCXCACHE",DFN,"$$LOCL^ORQQLR1(1234,110,119)","TIME")= When the data will be deleted from the cache.
78 ;
79 ; $$NOW^OCXCACHE = The number of seconds since the "beginning of time". Used to determine if the data
80 ; node in the cache is past its expiration date or not.
81 ;
82 ; It is very important that ORMTIME is running if this routine is being used.
83 ; ORMTIME calls OCXOPURG which calls PURGE^OCXCACHE that cleans out expired data
84 ; in the cache. This will keep the cache from using up all the available diskspace
85 ; in the Volume Set or directory that ^XTMP resides in. PURGE^OCXCACHE can be run
86 ; manually from a programmer's prompt if needed.
