You might to back to synaptic and click on the program and then you can
see what files were installed and where. It might be a cmd line program
without a link so you'll have to create one.

To run, open a terminal and type 'bwbasic'. To see a list of the
installed files, go into Synaptic, find bwbasic, right-click on it and
select 'Properties'. There's a tab in the resulting dialog called
'Installed files' - three guesses what that does

Another option is to open a terminal and type in:

"whereis bwbasic" (without the quotes)

This will return not only the location of the executable but any
associated files as well.

I'd never heard of 'whereis' before (yes, I
am still a relative newbie :-) ) but will be using it from now on -
*much* easier than my way :-)

Yes I will confirm your answer. Open up the terminal and type in
bwbasic
Just like in the old dos days.
