IsoDraw Macro to Change Color for all pens

[twade]

I am trying to create a macro that will search through my drawing the select all the pens and set the color to black. The pen names vary from drawing to drawing and that is were I am having difficulty. I am able to change the pen color if I know the exact name, but that is not always the case. I need the macro to seach all pens reguardless of the name and change the color.

Thanks for any help you can give me!

Probably over simplifying here, but would the following work? This sets them all to a single pen type. Would obviously lose line weight or styling.

Macro Pen4All

 Select All
 Set Active Pen "$ISO_THICK"
 Select None

End Macro

The problem changing them all to thick is I might have different line weights in the illustration and they would all then become the same size.
