Hi Matt,
I don't know how you read out the data, consider the following
from your code:
typedef struct {
char Department[20];
char Operator[20];
char RXNumber[20];
} DBRecord;
DBRecordType r;
// fill the record with data
StrCopy(r.Department, "123456");
StrCopy(r.Operator, "987654321");
StrCopy(r.RXNumber, "147258369");
you then write this structure out to the record.
The data you write will look like this:
123456\0 followed by 13 bytes of unknown content
987654321\0 followed by 10 bytes of unknown content
147258369\0 followed by 10 bytes of unknown content"
My point here is that the structure you allocate is 20 bytes for each
item. You fill out the structure, but there are still unused spaces ( e.g.
"1234567" only uses up 7 bytes of the 20 bytes allocation)
Also you don't zero out the structure after creating it, so there will be
random data in it.
so when you read in the data,you probably see the random data after your
strings.
I hope that helps,
Sebastian
