Hi Donnell,

BTW, -dev is meant for develpment of the internals of lon-capa, -users
is meant for questions of using the system and creating/mainting

No parameter is completely hardcoded. Anything in a .problem is just a
sugestion for that resource.

Go to the .page, click on the PPRM button that is above the .problem
in question.

If you have parts to the problem you will want to click on the 'Show
all parts' check box and click 'Update Parameter Display'

Scroll down to the 'Maximum Number of Tries' row 

Click on the link in the last yellow/bron column. (The one for 'Any
User, in course, for Resource')

Change it to whatever you want.

What makes you suspect that? I can't think of any reason that that
would be true.

Unless you have done something odd (like putting version numbers in
the resource urls in the .page), or explictly done something in
DOCS to lock things to a specfic version, Lon-CAPA always uses the
latest version of a .problem when showing it.

You can modify the .page in certain ways. The information is stored to
a combination of the .page's URL and the .problem's URL and the
internal id number of the instance of that resource.

Thus you can add and remove resources without it affecting any of the
other resources in the .page.

But if you change what resource URL is associated with a specific
resource ID in a sequence then yes the data will no longer be
available for that particular resource.

ALso if you create a whole new .page and put that one in the course
and remove the previous one, then also it will look like the users
will need to start over.

(The data is still there, and if you restore the proper elments back
into the course, the students will have done things that they normally
