2 Questions: list of variables & long lines

[Noel H. Bell]

I have two questions:

1. Is there an easy way to get a list of user-defined variables and
   their current values?  "who" prints out the variable names but
   not values.

2. When defining a variable, is there a line continuation character?  A
   single back-slash does not work and a carriage return causes a parse
   error also.  I would like this so that I can get decent looking 
   printouts of my m-files.

Thanks for any help or pointers to the manual.
