First is often useful for resetting the GetGlobal tool at the beginning of a loop. Note that if GetLocal is used in a loop, First is unnecessary. Note: If this module is used in the scripting language, the results are defined only if they are used inside a macro. #!N #!N See Also #!N #!N #!Lodone,dxall828 h Done #!EL , #!Lforemem,dxall851 h ForEachMember #!EL , #!Lforen,dxall852 h ForEachN #!EL , #!Lgetglo,dxall854 h GetGlobal #!EL , #!Lgetloc,dxall855 h GetLocal #!EL , #!Lsetglo,dxall940 h SetGlobal #!EL , #!Lsetloc,dxall941 h SetLocal #!EL #!N #!N #!Lxmod,dxall263 h Data Explorer Execution Model #!EL in IBM Visualization Data Explorer User's Guide. #!N #!N #!N #!F-adobe-times-medium-i-normal--18* Next Topic #!EF #!N #!N #!Lforemem,dxall851 h ForEachMember #!EL #!N #!F-adobe-times-medium-i-normal--18* #!N
