Conditional updating using SAS DDE

Hi,

I am updating an excel sheet using SAS DDE. The data is in following format,

date	a.xls	b.xls	c.xls
1	456546	456546	456546
2	5643	5643	5643
3	44	44	44
4	3	3	3
5	4656	.	123
6	454542332	454542332	567

Here, I am importing data daily from few XL sheets like a, b, c. So, each row represents data collected each day & cell, a particular value from the source XL sheet.

The requirement is that if y'day's data is not updated (i.e. cell is having '.'), I need to update it along with today's value. I am storing today's and y'day's data in a macro variable at start.Then I update today's row, then I will go through y'day's row and if any of the cell (R5:b.xls) is with missing value, will update it from macro variable.

I am seeing the value for y'day's missing value cell, being updated in some other cell.

Any suggestions?

You would have to show your code and attach a zipped example spreadsheet in order to know what you are doing.

Sure sounds like it would be easier to simply import the spreadsheet then, in a datastep, use update.

I have attached the part of the code, and have put the comments also. Code is running perfect for updating the Xl for today's date...only problem with if any missing data for Y'day date.

Thanks.
