To complete the previous tip in english I will tell you about the line-commands L and F. L and F works with excluded lines only. The Edit-macro ONLY produces a lot of those. Line-command X makes excluded lines as well as primary command X ALL.

Line-command F shows the first of the excluded lines. F2 shows the first 2 and so on.

Line-command L shows the last of the excluded lines. L2 shows the last 2 and so on.

If you aren't familiar with excluded lines it is good to know that primary command RESET brings it all back to normal. Excluded lines are always a part of your dataset or member, they are just not shown on the display.
