remove empty spaces

Dear all,

the report field "misc" A15 contains alpha numeric with spaces as separators.
I would like to remove all spaces in a report.

I got so far:
   A15;;B   removes the spaces on both ends, not within the field
   A15;;D   removes all spaces, shifts the content to the left
             and fills the rest to 15 with spaces
   A15;;DB  same as A15;;D

Ludwig Güthlein proposed to use subfield to remove the spaces. This
works.

Is there any other convenient way A15;;??? to remove all spaces.

Best Regards

Helmuth
