Thank you Roberto - just what I was looking for!!
I find many of the newer features aren't really well documented (if at all). Which is fine with the program because you can experiment. Experimenting is not so fine with GDL because it's rather less forgiving.
I've also discovered that by inserting the following in the 2D & Parameter script:
CALL "RequestPlanViewGlobals" PARAMETERS ALL RETURNED_PARAMETERS gs_symbtype_2D_m (this has gotta be all one line!!!!!)
With new Parameters:
gs_symbtype_2D_ (text)
gs_symbtype_2D_m (integer)
You can select the MV options from within your symbols and have them respond accordingly.
Nifty stuff, but some documentation would help.
Cheers
