When I use the scan function in the Rgui console it works as expected.
However it seems that when I put the same command in a script file it
doesn't wait for input.
Is there an option to scan to make it wait for input when used in a
script? Or is there possibly a different function that will do
Jim,
In Rgui there is a feature to create a new script so I open that
and get a blank editor. I put these commands in the script
MyNames = scan(what=)

Whether I ask Rgui to run the whole script as a script - not
sourced - it runs the first command, doesn't wait for input and then

There is an implicit 'print' when you type an object's name at the
