You can now refer to a specific kay=value from a pocket variable or any other delimited property (field) of an object.
For example: If you want to allow someone to edit a bit of text in an objects pocket known as 'greetmsg' (which is stored like this 'greetmsg=Ah.. nice to see you again' )
##editmsg:
var $caption to 'greet message';
var $fld to 'pocket.greetmsg';
say 'edit',"[$actor] starts to edit [$target]";
mode textbox;
This is the only time, at present, that you can reference a value from a string using the 'dot' concept. There is hope that this may extend to common setting and getting.. but manipulate will have to do for now. read the info about material
Im sure someone will make a natty little command where you can pocketedit the mouse with greetmsg
