The VA Cross-Referencer utility in Toolkit needs to reference several ^DD
nodes in order to cross-reference a package. Several of the referenced DD
nodes contain M code. They are inspected to find items such as
global/variables names and label /external references. Some of the referenced
nodes are the "LAYGO", "DEL" nodes. A specific example of a DD reference
S INDEL="" F G=0:0 S INDEL=$O(^DD(INDFN,INDF,"LAYGO",INDEL)) Q:INDEL=""
I $D(^(INDEL,0))#2 S INDC=INDF_"LAYGO"_INDEL_" ; LAYGO CHECK CODE",INDX=^(0)
The DD references are found in routines %INDX10, %INDX11, %INDX53.
