To use a dictionary in your graph, define the dictionary first: see Chapter 38, Dictionary.
To access the entries from CTL2, use the dot syntax as follows:
dictionary.<dictionary entry>
This expression can be used to
define the value of the entry:
dictionary.customer = "John Smith";
get the value of the entry:
myCustomer = dictionary.customer;
map the value of the entry to an output field:
$out.0.myCustomerField = dictionary.customer;
serve as the argument of a function:
myCustomerID = isInteger(dictionary.customer);
