You can also try to use global variables defined outside of functions or
macro declarations.
They will last, even if the macro is finished.
You can then just use an if statement or something else to check if you
already set a value or not.
If not bring up the dialog and so on.

That worked fine for me (even if global variables aren´t considered good
programming style sometimes)

Betreff: dialog box

Dear List

I have a macro that measures length and density within 2-300 manually placed
ROIs in a stack of images.  This part works fine.

I'd like to have a dialog box open that the macro looks at to get data about
the specimen that the images are of - whether the surface was milled or
polished and the orientation of the specimen.  I only have to set this data
at the beginning of a set of measurements, after opening the image stack.  I
tried putting a dialog in the macro, which works, only it asks me to set the
variables every time I take a measurement.

How can I make a dialog that I can set at the beginning, that my macro will
refer to each time it is run?  At the moment I have to edit the macro
manually each time I change images.  Not too onerous, but inelegant.

I'm OK at macro writing but haven't written a plugin yet.

The measure and dialog macros follow.

Thanks,

Mike
