Even (newer) MS-command.com supports this, so supporting this in
FreeCOM should be good.

Not necessary: program may parse CMDLINE by itself. And calling
getenv() is even easier, than accessing MK_FP(_psp,0x80).

As cited by Daniel Verkamp, there used (hidden) pointer to transfer

Also, (some) OpenWatcom tools support passing options through
environment variable:
set myvar=<myoptions>
wcc @myvar
WCL uses this mechanism, when passing options to WCC/WPP.
Using Tomcat but need to do more? Need to support web services, security?
