#!N #!N Functional Details #!N #!N GetLocal works with SetLocal to 
place objects in and retrieve them from the cache. GetLocal differs 
from GetGlobal in that GetLocal and SetLocal are used when the 
state maintained by the Get/Set pair should be reset when a 
macro containing these modules is reexecuted. In contrast, GetGlobal and SetGlobal 
will maintain state when the macro is reexecuted. Note that for 
a single execution of a macro (for example, throughout the execution 
of an entire loop), state is of course maintained by both 
GetLocal and GetGlobal. #!N #!I0 #!N #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!F-adobe-times-bold-r-normal--18*   
object #!EF #!EF #!I50 #!N specifies the object to be output 
by GetLocal if nothing has been placed in the cache (e.g., 
as on the first execution of a visual program) or if 
 #!F-adobe-times-bold-r-normal--18*   reset #!EF = 1. #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!F-adobe-times-bold-r-normal--18*   reset 
#!EF #!EF #!I50 #!N causes the module to output  #!F-adobe-times-bold-r-normal--18*   object 
#!EF . If this parameter is set to 0 (zero), GetLocal 
retrieves the last object placed in the cache by SetLocal (if 
there is one). Otherwise, the module passes  #!F-adobe-times-bold-r-normal--18*   object #!EF to 
the output. #!I0 #!N #!N #!N #!N The  #!F-adobe-times-bold-r-normal--18*   link #!EF 
output is to be connected to the  #!F-adobe-times-bold-r-normal--18*   link #!EF input 
of the corresponding SetLocal module. GetLocal should always be used with 
SetLocal, not with SetGlobal. SetLocal must be executed on the same 
machine as GetLocal (i.e., it cannot be distributed to a different 
machine). #!N #!N It is not necessary to use the First 
tool to provide input to the  #!F-adobe-times-bold-r-normal--18*   reset #!EF parameter of 
GetLocal inside a macro, since this is done automatically whenever the 
macro is reexecuted. #!N #!N A detailed description of the behavior 
and use of the GetLocal, GetGlobal, SetLocal, and SetGlobal modules can 
be found in  #!Lstates,dxall269 h Preserving Explicit State  #!EL  in IBM Visualization Data Explorer User's Guide.
