Software Installation
2-11 Getting Started
-
If you create an initdb.bat file, you must invoke it before invoking the de-
bugger for the first time. If you are using Microsoft Windows, invoke
initdb.bat
before entering the Windows environment. After that, you’ll need
to invoke initdb.bat any time that you power up or reboot your PC. To do
so, enter:
initdb
Modifying the path statement
Define a path to the debugger directory. The general format for doing this is:
PATH = C:\370TOOLS; pathname2;pathname3;...
This allows you to invoke the debugger without specifying the name of the di-
rectory that contains the debugger executable file.
-
If you are modifying your autoexec.bat file and it already contains a PATH
statement, simply include ;C:\370TOOLS at the end of the statement, as
shown in Figure 2–2 (a).
-
If you are creating an initdb.bat file, use a different format for the PATH
statement:
PATH=C:\370TOOLS;%path%
The addition of ;%path% ensures that this PATH statement won’t undo the
PATH statements in other batch files (including the autoexec.bat file).
Setting up the environment variables
An environment variable is a special system symbol that the debugger uses
for finding or obtaining certain types of information. The debugger uses three
environment variables named D_DIR, D_SRC, and D_OPTIONS. The next
three steps tell you how to set up these environment variables. The format for
doing this is the same for both the autoexec.bat and initdb.bat files.
-
Set up the D_DIR environment variable to identify the 370TOOLS directo-
ry:
SET D_DIR=C:\370TOOLS;
pathname2;....
(Be careful not to precede the equal sign with a space).
This directory contains auxiliary files (init.cmd) that the debugger needs.
