General ⇒ How to adjust fbox separation spacing?

[hzmonte]

I tried \setlength{\fboxsep}{1pt} for example but it affects only the horizontal spacing, i.e., the spacing between the text and the box border on the left and right sides, but not the vertical spacing, i.e. top and bottom.
My figure is written as follows:

Does any of the other stuff, such as parbox, math and tabbing, affect the failure of fboxsep to adjust the vertical spacing?

[localghost]

Of course a modification of the length \fboxsep affects horizontal and vertical spaces. Take the following example.

\setlength{\fboxsep}{0pt}
\fbox{%
  \rule{4cm}{3cm}
}
\setlength{\fboxsep}{10pt}
\fbox{%
  \rule{4cm}{3cm}
}

As you can see, horizontal space is not eliminated completely. At the moment I'm not aware of a workaround.

The fact that your code gives me some errors and the look of the result makes me suggest you the listings package for typesetting program code.
