very simple blackberry app

I need a very simple blackberry application that will make some changes to a .csv file based on the current time and date and on some user inputs.

## Deliverables

Please write me a Blackberry application which performs the following tasks when started:

load '[url removed, login to view]' file, which will already be on the device

(henceforth I will? use? track(i,j) to indicate the i-th element of the j-th column of this csv file, n to denote the row dimension and m to denote the column dimension of 'track', '<-' denotes assignment of a variable)

get the current time and date

if (current time < 6am) date? <- yesterday

if (m==1) olddate <- empty, otherwise olddate <- track(1,m)

if (date==olddate)? j <- m, else? j <- m+1

for? i in 2:n {

display track(i,1) (will be a string) and ask for numeric input,? convert letters of the keyboard to the corresponding numbers, so w is 1, e is 2 etc.

pressing the track-ball should enter/confirm the? input

track(i,j) <- input (this requires adding a column to 'track' if j=m+1)

}

exit the application

?

I will test the application on the BlackBerry Curve, but it should in principle run on any BlackBerry.

EDIT:

I have added two sample csv files, the second one is an example of what the file could look like after the application has been executed. Note that the application should be able to deal with more general files, so the number of rows and columns may be different.

In addition,

- The date should also be saved, so insert "track(1,j) <- date" in the loop above. I would like this date to be saved as the number of days since the year 0.

- Allow for empty inputs, so if the user simply clicks the track-ball after being asked for input record the input as empty (the sample csv file has empty fields)
