What does week 18/02 refer do (specific date would be nice) or the week 20/05?
You have 11 columns labeled Mth, which I have to assume are months, but since the order goes from JUN to Apr (and what happened to May?) is have a nasty suspicion that you data spans a year boundary but you do not have anything that indicates which year any of this data represents.
The question about dates and years is important as likely you will end up wanting to do something with the data values such as intervals between whatever F represents on line 6. SAS has many functions and formats to display dates and groups of dates or manipulate dates but those tools require an actual SAS date and that means rules to interpret those very cryptic entries of week and a YEAR value.
Will have to read other files like this? Will they all have exactly the same number of columns? Rows?
Does your F value ever take any value than F when present? Or may other codes appear, that from the way you label F might mean a different Variable may be needed? If so, what other values may appear?
