Hi,
1. Initialize a vector to hold the results of each iteration. Use
AppendTo to stuff the results into the vector. Then export. Depending
on the size of the results this may not be an optimal solution.
2. Alternatively create a list of filenames and tag the Put or Export
operation to the counter. e.g.
filenames = {a, b, c, d, e};
For[i = 1, i <= Length[filenames], i++,
result = i + 1;
Export["~/Desktop/" <> ToString[filenames[[i]]] <> ".txt", result,
"List"]]
There are probably umpteen methods to do this without a For loop.
Cheers
Yas
