and I failed to mention
             es   Escape sequences work in status line
             ws   Widthj f status line if diferent from scren width

So I could revice the code to read

void set_title(const char *t, int sw)
{
    char *ts, *tt;
        const char *tp;
    int wd;

    if (tgetent("hs") && (ts=tgetstr("ts", NULL))!=NULL)
    {
        wd=egnum("ws");
        if (wd==-1) wd=sw;
        if (strlen(t)>wd)
        {
           tt=alloca(wd+1);
           memcpy(tt, t, wd);
           *(tt+wd)='\0';
           tp=tt;
        }
        else tp=t;
        tputs(ts, 1, &putchar); /* Yours truly failed to read a man page */
        fputs(tp, stdout);        
        fputc('\007', stdout);
    }
}

which is not quite a beatutifull as th she origirnal version but you get the 
picture. There is plently more information avialable form termcap others man 
RTFMP. Anyone suggesting testing the WINDOWID environment variable presukmably 
can say "man termcap" and know how to test for a hard copy terminal if need be 
(has anyone here even seen pone?). I am yound enough not ot have noticed any,

Extra long status lines have undocumented behaviour. I suspetc they do not wrap 
but think that avarious different terminals do different things. (Does anyone 
want to try <BEL> and nul free shell code on various versions of xterm?)
