Mr Tony Preston of London asks "When I set up page marks in my screen it works perfectly well for paging down and up, but when my user presses the up arrow on the top prompt on the second screen the screen only moves up a line not a complete page. This looks incredibly messy. How do I make it work like in the Environment Window?"

This is a lot easier to do than to describe but I'll try to explain. It is really just an extended application of the Alt-H command.

Start painting the window and position the first prompt at the top of the window. Then press F4 to invoke edit mode on the prompt. Press Alt-H to show a page mark at the top of the screen and then without pressing return press the down-arrow key to move to the next prompt. Press Alt-H to show a page mark at the top of the screen and then without pressing return press the down-arrow key to move to the next prompt.

Repeat this until all of the prompts in the first logical window have had page marks added. When you get to the last prompt on the window press Alt-H to add the page mark and then press return twice.

This has had the effect of grouping all of the prompts on the first logical window together as a page.

Now move the second page so that the first prompt is at the top of the window and repeat the process above. Do this for each page and you should now find that your page logic will work as requested. Be careful however that hidden prompt labels are within the current logical window or your screen will jump about on redisplay.
