add data to end of specific line in text file

[hiNI]

Hello,

I am trying to add data to the end of the last 4 lines of the text file attached with data from the "Array to add".  On the 4th row (the 422.5800 entry), I would like to add the first entry from the "Array to add" entry, on the 5th row add the second entry from the "Array to add" and so on.  How do I go about doing that?

Any help will be appreciated.

Sincerley,

hiNi.

Are you just trying to append to the array adding a new column of data?  Just use the build array with a few transpose operations.  Normally build array just adds rows, this makes it add data as a column.

After re-reading your post I think this is what you actually want starting the append after the first 4 rows.
