[Dx4win] IOTA Status column

[Tony Lord]

Hi all, I am probably just being lazy here but can someone help? I am going
for IOTA awards. When I printing off the islands worked report, in the last
column the status is shown. In this column it shows either "S", "M" or "C".
What do these three letters mean? Would appreciate anyone's comments!!
