Hello,
this is not directly possible to substitute the array command from VnmrJ or VNMR in TopSpin.
The pendant tool is on the Bruker side paropt or the better popt utility.

PS If you are using XwinNMR you have no luck, there is no such a powerful tool like "array" impelemented in XwinNMR. ... "popt" is a bit better, but does not reach the capability of "array" in VNMR. I miss it too!
