- Shared NumberVar x;
- Shared StringVar y := “Hello, World!”;
Shared variables allow values to be used at any point in the processing of the report. Similar to a global variable, the shared values can also be accessed by subreports. This allows for a more direct method of comparison and allows the developer to circumvent the strict nature of the top-to-bottom report evaluation.
A shared variable can be defined, set, or recalled in any valid formula field. Their most common use is to store information that would otherwise be forgotten or inaccessible at a later stage in the report.
Define the variables within a formula field:
Shared NumberVar x := 1000; Shared NumberVar y;
Assigning the values is optional. To display the variable in a second formula later on in the report, the call is nearly identical:
Shared NumberVar x; x
