The value of a ''dynamic variable'' can be '''set''' at any point. Eg, ''prop.a'' is set to the text "A":

|'''set'''|prop.a|''to''|A|

To use the value of a ''dynamic variable'', use the @{} form.

Eg, here we use the action ''get'' to access the literal text "A" and compare it to the value:

|''get''|A|'''is'''|@{prop.a}|

Here we reverse things and use the action ''get'' to access the value of the ''dynamic variable'':

|''get''|@{prop.a}|'''is'''|A|

|''get''|@{prop.a}|'''is'''|@{prop.a}|

A cell may contain several ''dynamic variables along with text:

|'''set'''|prop.b|''to''|B|

|''get''|--@{prop.a}++@{prop.b}|'''is'''|--A++B|

|''get''|@{prop.b}+@{prop.a}|'''is'''|B+A|
