I defined a Name, called ARNG, that stores a range of cells.
I used the INDIRECT function to define the range and I passed as argument a concatenation of strings.
I would control the value of the Name ARNG.
In practice:

iniz = 5
nf = MID(INFO.DOC(1);FIND("]";INFO.DOC(1))+1;LEN(info.doc(1)))
ARNG =INDIRECT(nf1&"!$D$"&iniz&":$D$"&(iniz+45))

How can I control what value the Name ARNG assumes?
Thanks in advance.
