I won't be drawn into a discussion whether COMMON blocks are a good
things or not.

And anyway, I found out that you can list all variables using

help, names='*', output=out

For common block variables the output string contains the name of the
common block in brackets, hence the functionality I would like to have
is easily achieved by parsing through the output.

Ha!
