Hi Again...a bit of reading later and she's right mate!  I now know the '->'
operator, so another question.  Here's my structure, some code

--------------------------------------------
typedef struct {
float re;
float im;
} complex;

complex nick[4];
complex *fred;
fred=&nick[0];
---------------------------------------------

I can acess a member of struct with  "  (*fred).re " or "fred->im"
BUT how about adding an offset;

" ( i + parker )->re "   is correct,   but how about in the (*point ).mem
style ???

eg;

" (*parker + i ).re  "  is incorrect.

and  i+( * parker ).re give wrong results..Is the 'i' calculated as a float
(4 bytes )  ? not
an 8 byte 'complex' ?
