Xpress is not a language, neither is is a collection of commands. Xpress 
is the GUI (graphical User Interface) which applies to the enCore 
database. It has no commands. The enCore database consists of objects, 
which in turn have properties and verbs. Some of these verbs are 
commands (to be typed by a user in the command line/chat environment).

 From 2.1.1 to 3, and then from 4.0.1 to 5.

As Xpress is not a language, there is no specific syntax. The lines are 
MOO code, following MOO syntax. The example is taken from the enCore 
database, so the line per se is not covered in the Manual. The 
:announce* procedures may be covered, I don't know, please have a look 
by yourself. The action of passing a string from one verb to another, 
is, as well as string handling is.

Just a note: In order to write readable code and be on the safe side in 
argument numbers, I strongly recommend to concatenate strings first, e.g.:

   ann = tostr(" <", url, ">.");
   player.location:announce_all(ann);

enCore [Xpress] is GPL. You may edit anything, use it, pass it on. You 
MUST keep copyright notices and you MUST indicate your own changes. You 
may certainly discuss everything you want to since this is open source 
software. Discussing it is most welcome.

Good luck
