	here's the way I've done it so far:  

	I've used readdir( DIR *d) and more to find the text[n].txt 
	file names.  then, in a 1998 c++ file I find these txt names
	by using essentially  {psedocode): 

		infp = fopen(filename[i], "r")
		   while (fgets(buffer[i], sizeof buffer, infp))
		fclose(infp);

	that's an immediate re-translation from c++ to C.

	thanks, polyt.  I will put this last of several pieces of code
	together until I've got my several buffer[i] copied into the 
	GTK label[i].

	FWIW: the reason I want to have these several "labels" in a
	wudget//widows is to make the program less clumsy.  it does
	work as-is; but it can get clumsy.
