Kay,

I found the issue.

Not all the macros were being passed to the main display from the command line. I had to quote the entire string of macros on the command line.

Hi:

>I succeeded in passing macros on the command line, now I want to open a generic display from this top level display and selectively assign one of the macros. I am using an action button to open the related display. I have tried assigning the generic macro to one of macros passed from the command line (GENERIC_MACRO = $(MACRO1)), in the related display dialog box, but the macro doesn’t expand. The new screen shows the value of GENERIC_MACRO as $(MACRO1) rather than the value of $(MACRO1).

This works for me:

In a display, define MACRO1=Value 1, MACRO2 = Value 2.

Then add for example a label with text "You picked $(PICK)".

I can now open that display from the command line with one of

-resource file:/path/to/file?PICK=Something

-resource file:/path/to/file?PICK=$(MACRO1)

-resource file:/path/to/file?PICK=$(MACRO2)

and as a result the screen opens with "You picked Something", "You picked Value 1" respectively "You picked Value 2".

In the last case, when I open the context menu on the display to open the display information dialog, then check the "Macros" tab, it contains:

MACRO1 = Value 1

MACRO2 = Value 2
