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.
