• The source code pane, located in the middle of the Xbrowse win-

dow, is the largest area of the window. This pane displays the

current source code.

• The information pane is located at the bottom of the main Xbrowse

window and provides information about the status of Xbrowse.

You can also type equivalents of the Xbrowse commands for many

menu options in this pane. (A list of these commands is available

through the Help menu option.)

To open a ﬁle, position the cursor on the File menu button and press the

left mouse button to open the menu. With the menu displayed, click on

the Open option. A window is displayed on which you enter the name

of the ﬁle (or ﬁles) to be opened.

A common activity while browsing code is to look for various types of

objects. The following list names a few of the objects you can locate by

Xbrowse:

• calls and callers

• common blocks (Fortran only)

• loops

• routines

• variables.

You can look for routine-based information with the commands in the

Find menu. These commands let you look for ﬁle-based or application-

based information. Most commands work in a similar manner, so trying

a couple of searches will give you an idea of how to ﬁnd objects in your

code.

Call trees make it easy to see the structure of your code through a

clear graphical format. The Display menu provides the following two

commands for generating call trees:

• Call Tree

• Caller/Call Tree

Xbrowse gives you visual clues to help you identify various parts of

your code within the call trees. External routines are shown in green

and intrinsic routines are shown in yellow. An external call is one for

which Xbrowse does not have the source code loaded.

The command Call Tree produces a static call tree of loaded source

code. The name of the application or the ﬁle used by this option is

shown at the top of the display. The called routines and subprograms

are displayed in the middle.

The small, empty boxes following some nodes (routine names) on the

tree indicate subtrees that stem from these nodes. To open the tree one
