dump info into a text file

For example 2 input Nand, A,B output , vcc , vssx and internal net (n2) will be the m0 layers. I need info like in a text file.

n2 co ordinate

vssx (co ordinate)

a (co ordinate)

b (co ordinate ) .

I found similar code in cadence form . Can you help me on this

 procedure(printPts()
let(    (type
    (cnt 0)
    (objList geGetSelSet()))

foreach(obj objList
    ++cnt
    type = obj~>objType
    case(type
        ("inst"
            printf("%s %L at %L\n" type obj~>xy))
        ("rect"
            printf("%s on layer %L at %L\n" type obj~>lpp obj~>bBox))
        ("polygon"
            printf("%s on layer %L at %L\n" type obj~>lpp obj~>points))
        ("path"
            printf("%s on layer %L at %L\n" type obj~>lpp obj~>points))
        ("pathSeg"
            printf("%s on layer %L at %L\n" type obj~>lpp list(obj~>beginPt obj~>endPt)))
        ("label"
            printf("%s on layer %L at %L\n" type obj~>lpp obj~>xy))
        (t    printf("%s not defined\n" type))
    )
)
printf("%n objects selected\n" cnt)
); end of let
); end of printPts
