According to one embodiment a method and apparatus for displaying the path
of a computer program error as a sequence of hypertext documents in a
computer system having a display is disclosed. The method includes
displaying a first function in the control-flow path of the error as text
in a first region on the display. Subsequently, a first hypertext link
marker located within the first function, and associated with a second
function called by the first and also lying on the error's control-flow
path is selected. Thereafter, the second function's text associated with
the first link marker is displayed in a second region. The second region
is positioned in the first region such that the text of the first
document is not obscured. The second region includes a first tab area
that surrounds the first link maker after it is selected. According to a
further embodiment, the method also includes selecting a second hypertext
link marker located within the second function, corresponding to a third
function called by the second and lying on the error's control-flow path.
Afterwards, the text of the third function associated with the second
link marker is displayed in a third region. The third region is
positioned in the second region such that the text of the second document
is not obscured.
