I guess I didn't say how long I waited before posting.  The mail went out
three weeks ago.

The following program will also demonstrate this:

	#include "stdio.h"
	main()
	{   FILE *output;
	    if (output = fopen("xyz","a")) {
		/* To overwrite add an fseek() here */
		fprintf(output,"This line was appended\n");
	        fclose(output);
		}
	    else {
		printf ("Can't open file\n");
		}
	}

I used Manx 3.6a, but Lattice should work too.

To use it create a garbage file named "xyz" (like Dir >xyz), LOCK the
partition containing "xyz", execute the program and look for the message
at the end of the file.

The Dillon/Drew shell (version 2.07m at least) exhibits the problem when
using >> to redirect output.  That's how I originally discovered it.
