Re: append

Took a quick look at the source for implementing append mode.  I think we could just add the following and have it working:

/common/_fopen.c:

in amode_to_bmode add this code to the switch statement:

  case 'a':
    binmode = O_APPEND;
    break;


/atari/open.s:

add/change the filemode handling code:

l2:     cmp     #O_RDWR
	  bne     l3
	  lda     #OPNOT|OPNIN
	  bne     set

l3:     lda     #OPNIN|APPEND
	  bne     set

I think that is all that is required, isn't it?  I don't know that I will be able to build the libraries without Unix... I wonder if one of the atari developers can compile it... I'll gladly test it!

PS.  sorry for all the traffic lately...
