Get it permanently out of the way by installing 4dos, now available
free at jpsoft.com.  The command line limit will then be 511.  You
might decide to use 4NT and pay for it, if you so choose.

You will no longer have the complete command tail available at 80
in the PSP, but very few systems use this anyhow.  If you really
need the whole line you can find it in the environment under
"CMDLINE" and there may even be a pointer to it in the PSP
somewhere.  I doubt you are using the pre-parsed partial FCBs at 5c
and 6c either. :-)
