Hi

so here are some very fast ones based on pointer operations which do
work on sub structures too

delete_tag
http://www.fz-juelich.de/icg/icg-i/idl_icglib/idl_source/idl _html/dbase/delete_tag_dbase.pro.html

add_tag
http://www.fz-juelich.de/icg/icg-i/idl_icglib/idl_source/idl _html/dbase/add_tag_dbase.pro.html

replace_tag_value
http://www.fz-juelich.de/icg/icg-i/idl_icglib/idl_source/idl _html/dbase/replace_tagvalue_dbase.pro.html

rename_tag
http://www.fz-juelich.de/icg/icg-i/idl_icglib/idl_source/idl _html/dbase/rename_tag_dbase.pro.html

If you like to read examples in german may be you are interested in
reading a book about our library
