TJaMGraphics
------------------

There are a number of significant changes to the TJaMGraphicsPackage this release. The principal operational change is that TJaMGraphicsPackage now contains the JaM typescript. To run JaMGraphics:
Bringover /p TJaMGraphics
Boot your Client volume and make a new checkpoint. (will go away next Cedar release)*
To the UserExec type:
run TJaMGraphicsPackage --you can modify your user.profile to eliminate this step
JaMGraphics
This will get you a JaM typescript and a JaMGraphics viewer. Each time the command JaMGraphics is executed in the UserExec you will create another pair of viewers. Run Graphics.jam as usual to get the graphics commands. Note that all instances of "(tjamgraphicspackage.bcd) .loadbcd" and "loadg" should be removed from your JaM code.
If you have the following lines in your user.profile, typing "JaMGraphics" to the UserExec will automatically run TJaMGraphicsPackage if necessary:
RegisteredCommands: "
JaMGraphics \"Creates a JaM typescript.\" TJaMGraphicsPackage
"
It is now possible to backup the JaMGraphics viewer with a GraphicsList, which means that the viewer will be refreshed when you move the window. See the documentation for details.
TJaMGraphicsPrivate.EstablishNonViewerContext has been replaced with something better. See the implementor and the interface TJaMGraphicsContexts.mesa for details.
* There are problems with the versions of start.jam and util.jam included in the Cedar release. These files, which are critical to the operation of the JaM typescript, are normally run by Tioga when it is started. While it is sufficient to run start.jam from the JaM typescript, if you boot and make a new checkpoint you will get get these files properly installed once and for all.
Video

DF file: Video.df
Documentation: none
