and Hello is shown also when cancel was pressed. So the script execution does not stop.

Your explanation sounds reasonable, but why does the script indeed return 'Cancel' if run from the command line? I discovered this by accident as I use an external editor which launches ImageJ via the command line when writing or testing new macros.
But I will assume that checking for both an empty string and 'Cancel' will suffice.

the problem seems to be that <cancel> or <escape> terminates a running macro or (in this case) script, as soon as "gd.wasCanceled()" is called.
You can determine determine the 'canceled' condition by checking for an empty reply String.
This it is a rather nasty hack, however, not necessarily guaranteed to work in the future if the mechanism of handling the 'canceled' condition should change.

I don't understand why that should make a difference. It also works if I copy the assembled string as printed in the log window and run it from a text window as javascript.
