Testing to Relative coordinates in GDL

[Bruce]

How can I test the rotation of a 2D symbol I've scripted against the rotated screen orientation, as opposed to the original rotation?

I can't find anything in the GDL reference about rotated orientation.

[Laszlo Nagy]

Use the TEXT2 GDL command in the 2D Script to display the SYMB_ROTANGLE global variable.
I suspect the orientation change will have no effect on the value returned by this variable but you should try to make sure.

TEXT2 0,0,SYMB_ROTANGLE

Edit: You may want to check out this post, Frank Breister mentions a bug related to exactly this GDL global variable.

Yeah - this gives the rotation angle based on the default orientation. Ta anyway

[Laszlo Nagy]

Ah, you want to do something that is always horizontal regardless of the orientation rotation?

[Bruce]

Yeah, something like that.

[Laszlo Nagy]

I see.
I checked the GDL Docs for both AC13 and 14 and there does not seem to be such a GDL variable:

You may want to create a wish for that.

Aha! Found it.

Page 297 of the v13 GDL reference guide:

REQUEST ("view_rotangle", "", angleViewRotation)

Returns the rotation angle of the current view.

Cool

[Laszlo Nagy]

Oh, that's good you found it.
I thought it should be a Global variable, I didn't think that it could also be obtained by a REQUEST function as well.
