Go ahead and use Griswold & Griswold.  Icon is mostly backwards
compatible with its former incarnations.  You'll notice that co-
routines came and went and came back again from version 5 to 7.
String scanning no longer operates with simple global variables
&pos and &source.  These variables still exist.  However, their
scope is a bit different.  No need to worry about the specifics.
There are a few nice features, like faster and cleaner options
3 and 4 for sort.  We now have math functions that used to be
part of the library (sin, etc.).

In general, don't worry about the differences.  If something seems
awry - which is unlikely - post.  You certainly won't be the only
one whose had questions :-).  The version of Icon you are using
will certainly have documentation to go with it.  When you feel
comfortable enough with the language, just browse through them.
They are well-written and pretty concise.  You quickly get caught
up on the additions that have been made to the language since ver-
sion 5.
