I am on windows 7, 64 bit, using Maple 17.02. When opening the command line Maple, and typing:
But on the GUI, it works:
and I get a new window open with the list of package.
In the command line, it works if I use ?index,package; i.e. without the extra `s` at the end.
On a side question, I was looking at a Maple book, where it said to use ?index[packages]; but this no longer works, even in the GUI, and had to use ?index,packages; syntax. I wonder when this change happens. The book is old, using Maple 7.
