I've used Zap and StrongEd, but have multiple memories of watching
somebody destroy a piece of code by editing it without thinking.
Before a certain version StrongED stripped all line numbers killing
any code with GOTOs in it without warning first.

When *COPYing on RISC OS or using the Filer (which is just a sort-of
front-end to *Copy) the only metadata transfered is the load and
exec addresses and access byte. So, when copying /from/ Level4
all you get is the load/exec address, when copying /to/ Level4
all that is written is the load/exec address. And, as Level4
runs on top of a RISC OS filing system it assumes that that
filing system only has load/exec, so throws away anything else.

Of course, if those load/exec addresses happen to have a 5-byte
datestamp in them, then the RISC OS filer sees them as a datestamp.
Also, Level4 supplies that date in the NetFS moddate (X%+15/16)
when responding to ObjectInfo queries.
