Yes, just like you have it. At runtime, the label of a page called "page" would appear.
Can i use this in a text or data expression to display page label: page.label
Can i use 'page' as a variable? or should i use actual page name?
When i use any of the above I get the "cannot find an identifier ...would you like to create a tag ..." pop-up.
any breadcrumbs?
Thank you for the help.

Yes. I think you can use it anywhere that is expecting string data. But, use the equal sign in front of it, then the actual name of the page followed by a period and the 'label' or 'desc' identifier.

I think it will have to be an actual page name.
What is your intended purpose?
EDIT: Play around with the attached example in the emulator and pick it apart to see if it helps you.

Awesome. very useful stuff.

I'm struggling to log an event when the data station powers up. Here is my method:
Increment a tag ('Startup') on power up. (page, global actions, 'on startup')
Enable alarm1 for 'Startup'. Event Mode = 'data mismatch'. Alarm value = last value of 'Startup'. Trigger = Edge triggered.
I never get an event.
However, if i increment 'Startup' while emulating, an event is logged.
Seems like a timing issue. solution?
thank you

Make your startup routine complex code, and add a sleep() command before you increment. ie...
Sleep (1000);
Startup++;
If you don't need a startup count, you could also make this a non-retentive flag tag (edge triggered event on). Set it to 1 after the Sleep().

I don't know of any sample code library. Depending on how comfortable you are with C style programming, I suggest that you look through the functions help PDF, to familiarize yourself with them. Also, the functions are shown in the systems tab (bottom right).
I've found, that with the small samples in the help file, and a little playing around in the emulator, that most of it is easy to learn. If you really get stuck, you can ask here, or call Red Lion. The key is to know what is available.

Do a search on this site. Several people have posted Code from projects they are working on.
