Hi, I changed the perl script of
'scl/dencker/testing/examples/simple syntax check 1.problem' The first version is obsolete, written for another purpose. Take always the current version ... I know the following way to see the code: 'Course Editor' -> 'Published Resources' -> Import Then you can choose on the top 'Display Options'. Select 'Source Available' and 'Update Display'. Then there will be a link to the 'Source Code' to the right of the problem name. I don't know whether there are other possibilities. - Peter On 10/31/2013 12:41 PM, Angus Findlay wrote: > Peter, > > Thank you for your help.
