Hi Statalisters,
I know this sounds quite trivial. I am surprised as well.
I currently use Stata16 and I have been using the "putexcel" command since 2013 with Stata13.
I suddenly realise that my "save-time" putexcel export command is no longer responding.

Here's the code:
corr var_x1 var_x2 var_x3
return list
matrix list r(C)
putexcel A1=matrix(r(C), names) using C:\Users\ng\Desktop\ICT.xlsx, modify

This is the same code I've always used but suddenly returns the below-mentioned error which was never the case:
using not allowed
r(101);

I tried with Stata13 and Stata15 and got the same error.
Kindly assist in this regard.
Thanks.
Ngozi
