Another Amiga Question:
   In my desperate attempt to create a way for a user to input a filename
(from my C prog) I have discovered that string gadgets can be attached to
Requester windows.  That, unfortunately, is my problem.  I used the
InitRequester(MyRequester) to initialize a requester structure, and then
filled in the position. (eg MyRequester.Width = 100, etc).  I then
created a struct Gadget MyGadget.  Operating from the RKM v2 intuition.h
documentation, I filled in the Gadget.Type with STRGADGET.  I assume
this means a string gadget which lets you input a line of text.  Now there 
was an UNDOCUMENTED field in the Gadget struct that I didn't know what
to do with.  It is called "SpecialInfo" and the RKM merely says,
its (paraphrased) "a special data pointer required by String Gadgets".
   Of course, no where else anywhere was this thing mentioned.  So I
set it to NULL.
   Then I did a ReqWindow = BuildSysRequest( and for the parameters I used 
the current window and the size info, and three IntuiText thingies.
Then later on in my program, when I wanted the requester displayed, I did
a Request(MyRequester,ReqWindow).

Results:  Immediately after the BuildSysRequest got executed a requester
popped up that had a Positive gadget, a Negative gadget, but no goddamn
string gadget.  The Amiga never waited for me to call the Request() function,
instead it built the window when BuildSysRequest was called.  The Request
window had no close box or other way to kill it - clicking on the Pos or
Neg gadgets did nothing except inverse video the gadgets.
   According to my lousy Sybex "Amiga Programmers Handbook" *supposedly*
no requester window will be generated until Request() is called.  Obviously
that was wrong...

My Question:  Can anyone tell me (a) how to use String Gadgets, (b) how
to incorporate these gadgets into Requesters, and (c) whether anyone has
JUST the Intuition Manual for sale...

Sample code would be VERY nice, but english is ok, too.  I have V1.1 of
Kickstart and Workbench, and Lattice v3.3.

Oh by the way:  when my program actually did get around to executing the
Request() function, the amiga emitted a low sustained beep, and the screen
cycled blue and white 2pixel high bars for about 30 seconds.  Then it auto
rebooted.  My apartment-mate was impressed.  "Gee, you can turn the screen
into a barbershop pole!"

Thanks very much for reading this long tale of frustrations :-)
