I hacked that renice for the 286 to use kmem values stored in a
file (hence uxlst) since the original 286 renice (written by
Mike "Ford" Ditto) took so long to run on my 8MHz machine.
What I also did (since I use a BSD machine too) was to
change the syntax of the command to compky with the BSD
syntax.

renice 0 <pid> sets the SysV nice factor to 20
renice -20 <pid> sets the nice to 0
renice 19 <pid> sets to 39

Sorry for the confusion.  I am posting this since others may have
gotten confused as well.

If you want to become compatible with sys V values, in renice.c
find and change the following :

/* in main() as it is now */
    value = atoi(argv[1]);
    if(value < -20)
        usage();
    if(value > 19)
        usage();
 
    value += 20;
 
/* in main() make it: */
    value = atoi(argv[1]);
    if(value < 0)
        usage();
    if(value > 39)
        usage();
 

/* in renice(), as it is now */
    printf("%d: old priority %d, new priority %d\n",
        pid,oldnice - 20,value - 20);

/* in renice() make it: */
    printf("%d: old priority %d, new priority %d\n",
        pid,oldnice,value);

I thought I had documented the "wierd" syntax in the README file.
If you got the program without the README file, I'll be glad to repost
the shar.
