What the Debugger Does
During Invocation
In some circumstances, you may find it helpful to know the steps that the
debugger goes through during the invocation process. These are the steps,
in order, that the debugger performs. (For more information on the environ-
ment variables mentioned below, refer to your installation guide
.)
The debugger:
1) Reads options from the command line.
2) Reads any information specified with the D_OPTIONS environment vari-
able.
3) Reads information from the D_DIR and D_SRC environment variables.
4) Looks for the init.clr screen configuration file.
(The debugger searches for the screen configuration file in directories
named with D_DIR.)
5) Initializes the debugger screen and windows but initially displays only the
COMMAND window.
6) Finds the batch file that defines your memory map by searching in directo-
ries named with D_DIR. The debugger expects this file to set up the
memory map and follows these steps to look for the batch file:
-
When you invoke the debugger, it checks to see if you’ve used the –t
debugger option. If it finds the –t option, the debugger reads and
executes the specified file.
-
If you have not used the –t option, the debugger looks for the default
initialization batch file.
If the debugger finds the file, it reads and executes the file.
If the debugger does not find the –t option or the initialization batch file, it
looks for a file called
init.cmd.
