Below is the specification of the References assembler:
$REFERENCE(NOME_REFERENCIA)$ assembler
To find the value of a reference just use the assembler $REFERENCE(NAME_REFERENCE)$.
If the reference information is being searched in the reference register itself, it is not necessary that the completed formula is $REFERENCE(NAME_REFERENCE)$, but only $NAME_REFERENCE$ can be used.
If the reference to be used is at levels above, just add P. at each level.
Example: $P.P.Reference(NAME_REFERENCE)$ - In this case, the reference value of the item's parent's father will return.
