Hi folks,

Really hopeing someone will look at this and give me some clues
as to where to start looking as I'm Stuck.

I have some code that compiles/runs fine under NT and 95. Trouble is
I want it to run under DOS (It's a shop till system).

I have this structure defined :-

typedef struct {
 char product[PRODUCT_LEN];
 int stock ;
 int price ;
 char bar[BAR];
 int active ;
 int quantity ;
 char vat_code ;
} SellRecord ;

When I define an array of this structure I find I can can define an
array of up to 6 and everything runs fine. If I define the array with
a size of anything greater the program fails with this error message :-

Exiting due to signal SIGSEGV
Page fault at eip=00004023, error=0006

It looks like memory to me, which would explain why it runs
under NT/95 but not dos, but I'm danged if I can work out what to
do next.

This is running under Caldera DR-Dos 7, but I have the same problems
with MS Dos.

Any help would be really appreciated.

Thanks,

John.
