Since the HP 95LX runs Microsoft DOS version 3.22, compilers, assemblers, and
debuggers compatible with this version of DOS can be used to develop software
for the HP 95LX. Some development packages such a Turbo-C from
Borland support remote debugging over a serial interface. This configuration
works on the HP 95LX and is very useful for certain types of
software development.

Because the HP 95LX is a relatively small PC, users of off-the-shelf tools
should understand what overhead is built into the USE of their tools.

For example:

	* Run time support libraries sometimes include modules that are not
	  needed by the main program.

	* Users building HP 95LX system-manager-compliant programs need to be
	  aware of any library initialization code their package automatically
	  includes in programs they build. Much of this sort of initialization
	  code is incompatible with the HP 95LX System Manager. Steps can
	  usually be taken to use library routines that do not require
	  initialization.

Some software-development activities benefit from emulating the HP 95LX on a PC.

The "Soft-ICE" package from NU-Mega has been used to facilitate emulation
of the HP 95LX on a PC.
