Optional Files
†
init.cmd is a file that contains debugger commands. The version of
this file that’s shipped with the debugger defines a ’370 memory
map. If this file isn’t present when you first invoke the debugger, then
all memory is invalid at first. When you first start using the debugger,
this memory map should be sufficient for your needs.
Later, you may want to define your own memory map. For informa-
tion about setting up your own memory map, refer to Section 7.2,
Memory Mapping and Defining a Memory Map, in the TMS370 Fam-
ily C Source Debugger User’s Guide.
In addition to init.cmd, there are several other .cmd files in the maps
directory. These .cmd files define memory maps for standard ’370
devices. If you want to emulate a specific device, copy the appropri-
ate .cmd file into your init.cmd file.
init.clr is a general-purpose screen configuration file. If this file isn’t
present when you invoke the debugger, the debugger uses the de-
fault screen configuration.
The default configuration file (.clr extension) is for color monitors;
another file (.mon extension) can be used with monochrome moni-
tors. Several of each type of screen configuration file are included
in your screens directory. When you first invoke the debugger, the
default screen configuration should be sufficient for your needs. Lat-
er, you may want to define your own custom configuration.
For information about these files and about setting up your own
screen configuration, refer to
Customizing the Debugger Display, in
the TMS370 Family C Source Debugger User’s Guide.
Due to the 640K-byte memory limitation under DOS, it may not be
possible to load and/or debug large applications with the DOS ver-
sion of the debugger. The Windows version of the debugger will
make use of any extended memory available on the PC.
† Included as part of the debugger package, these files are available on the C-source debugger
product disk but have not been copied by the installation process.
