IDL Syntax ?

[Eric Kihn <kihn(at)mindspring.com>]

I'll hope this isn't too FAQ but...

1) Is there an escape sequence for IDL strings? Ie if what I want is

Hello <return>
There.

In one string what should I be using. I guessed at \n (old habits die
hard) and failed. A manual and on-line help
search failed also..

2) When using Map_Set I see lots of keywords for rotation, orientation,
etc but nothing to restrict the displayed lat lon. If what I want is a
lat-lon box (Not global) with continent overlays for example should I be
using something else?  I'll gladly take and RTFM if someone can say
which FM?
