Hi Jürgen, Blake, APLers,

wouldn't it be a low effort approach to switch to )DUMP-format as
general workspace file format, having at the end an optional
⍝-area containing <StateIndicator levels="1"> from the current

If this ⍝-area is present loading the file, it gets parsed and loaded,
otherwise it is loaded as currently without state indicator.

just my 2cents - :) Otto
