Frequently Asked Questions List

Q: Can I run VisualWorks remotely?

A: VisualWorks can only be executed locally. That is to say, open a local XTerm or Command Tool to run it, instead of on running through an acme machine.

Q: Do I need to do the source file setting every time?

A: The source file setting is necessary whenever you want to run VisualWorks on the Rich Suns. This setting is not saved between sessions.

After you enter the file name and press "Accept", if nothing happens but the "Accept" button is disabled, it means the source has been set correctly. Then you can press the right mouse button anywhere in that window and use "Close" to close that window.

The setting for Source on most Rich Suns is:

/remote/sun4m/sun4m/lib/visual/image/visual.sou

/remote/sun4c/sun4c/lib/visual/image/visual.sou

If you can not get your setting accepted with either path, ask for help from your TA.

Q: Should I print out the labs beforehand?

A: Probably not. You are highly encouraged to open a Netscape window when you are working on your labs, instead. The lab instructions may be changed right up until the lab session begins.

Also with the web page opened, you can copy/paste code from the instructions.

Q: How should I exit VisualWorks?

A. Do not log out of the machine before you quit your VisualWorks. You need to file out the code that you have written. (Hint: keeping all your code in one catagory will make this much easier). You MUST file out your code before exiting VisualWorks.

Do NOT save when you exit from VisualWorks. Saving will save the entire VisualWorks image into your own folder. You don't have enough disk space for that.

A: You need to send the file with a subject. Be sure to use the -s option of the mailer. The command line should look like this:

cat filename | elm -s "TI,Lab1,<your studentNumber>" cs2390@prism.gatech.edu

Example:

cat filename | elm -s "TI,Lab1,355678990" cs2390@prism.gatech.edu

Note that there are no spaces in the subject line!

When you have two files to turn in, use a command like:

cat filename1 filename2 | elm -s "TI,Lab3,<your studentNumber>"cs2390@prism.gatech.edu

Now, you know how to turn in three files, don't you?

This is same process you will use for the project reports in the future.
