Unused selects in SHTOLO

[David Price]

Hi Rob,

Are you asking for a change to the EXPRESS LRM itself or a change in the
EXPRESS tools as a convenience?

Cheers,
David

Hi Günter
I think that there should be an option to prune unused constants, types,
functions and procedures from a long form as well.

Regards
Rob
