    No one gave me a solution last time, so here I am again to state the 
problem a little more clearly. Thanks to a new utility, you can see firsthand 
the kind of frustration I'm getting here:

===============================================================================

$type q.c
char *wr(a)
int a;
{
char b = "Arf!";

return(b);
}

main()
{
 printf(" %s ",wr(4));
}
$cc q
$link q,sys$share:vaxcrtl-options-file/opt 
$run q
%SYSTEM-F-ACCVIO, access violation, reason mask=00, virtual address=00000000,u[MF|L PC

    I am certain that this code is perfectly legal within K&R syntax rules. 
The error here seems to be that I am linking the wrong way. I am under VMS 
4.7, and all the C linking rules have been changed. If anyone knows what I am 
doing wrong here (I am trying simply to get my function to return a pointer to 
the first character in a string - the function declaration I am using is the 
same style K&R used for their fgets) PLEASE let me know - this is getting 
downright aggravating.
    By the way, this code was ported to Turbo C where it also refused to 
compile properly - the best I've gotten under any system was the same garbage 
every time I run it. Has someone changed all the declaration standards while I 
wasn't looking?
