Dear Experts:

A workbook with several worksheets has numerous workbook-level names,
which all have the following synthax:

_##_###_##_## (e.g. _90_237_44_44)

I would like to run a macro that changes all the above workbook-level
names to the following synthax:

##-###-##-## (e.g. 90-237-44-44). That is the first underscore has to
be dropped, all the other underscores have to be replaced with
hyphens.

Help is much appreciated. Thank you very muc in advance.

Regards, Andreas
