I almost replied before, but I would not have had the correct suggestion.  But
maybe someone else would like to know this.  By reading Inside Macintosh about
SFGetFile (and SF etc.), it appears that in C you can pass a file-type
selection array of length one by '1, "TEXT"' -- but, the code uses a ".w"
instruction, and you have a .5 probability of an address error.  (Maybe that is
an ID=02 error??)  I found it on my second use of the trick.  Now I do it this
way:
  long ftl;
  . . .
  ftl = (long)'TEXT';
  SFGetFile( . . . 1, &ftl, . . .
Even making your C code more like Apple's Pascal may not guarantee the array
starts on an even address, so you should probably union the character string
with a long to insure the correct boundary. Too bad Apple picked Pascal, such
poor handling of variable length arrays and strings.  And it looks like the
Intel processors have at least one advantage over Motorola -- no odd address
bombs.

PS:  Inside Macintosh also lies when it says "prompt" is not used in
    SFPutFile.  Of course, the garbage text in your dialog the first time
    you believe IM tells you to not believe IM.
