Survival strategies for markers?

Survival strategies for markers?

[Thorsten Jolitz]

Hi List, 

when markers are exposed to extreme conditions

 - copy buffer substring (with marker m) from buffer A to temporary
 - buffer B
 - modify buffer content in B
 - change major mode in B

how do they survive? 

Or, more prosaic, can I do these things and somehow copy (bufferlocal?)
m from A to B, or do I have to take an indirect approach remembering m's
position in A in a global var and set a new marker at that position in
B (or so)?

cheers,
Thorsten

The later.

Markers are independent objects, they're not embedded in strings.
