Thanks for clarifying this! I was not aware of this usage.

Is there a way to check if two user marks are on the same line?
(This was occasionally convenient for me with the html parsing.)

Reading the docs I fear I do not understand the user-mark mechanics
completly, especially move_user_marks.

define fun1( m){
...
move_user_mark( m) % m= create_user_mark() would not change the m in calling
space
...
}

m= create_user_mark();
fun1( m);
goto_user_mark( m); % m redefined in fun1()

Is my understanding correct?
Thank you in advance.
