repetitive procedures

Dear friends.

One more time I come to appeal to your aid. My Autocad has an installed application that it allows to break a topographical map 1:25000 in some maps of other scales. Here's an example: To divide a topographic map of 1:25000 in several of 1.1000 results in a matrix of 20x20. This implies that the application that I have installed and that it is activated through in the line command for NewSheets, needs that click in a point in the way of each letter of 1.1000 and to give ok, about 400 times.How can I facilitate this process by clicking just the first map (upper left) and he go through all the rows and columns of the array automatically. I apologize for my bad English. A hug and thanks.

What is the 'application' named?

There is not a commercial application. It was designed by the installer of Autocad. The only wish is that through a first point and an ok button it performs a loop over the twenty rows and of the twenty columns. Best regards.

In a simplified form. I need a loop inside another loop that traverses a map points in 20 rows and 20 columns and run a given command in each of the points.
