How to create and handle a structure?
A structure is a type of variable made of other variables. For example, an "Address" variable can be made of: - Name of my company
- Name of contact
- Address
- Zip code
- City
- Country
This allows you to pass as parameter to a procedure a variable created from a structure instead of passing as many parametes as the number of elements found in the structure. To declare a structure, use the following syntax:
StructureName is structure
Member1 is <type of variable>
Member2 is <type of variable>
...
END
For example:
stAddress is Structure
CompanyName is string
ContactName is string
Address is string
PostalCode is string
City is string
Country is string
END
To use an existing structure, you must: - Declare a variable (same type as the structure).
- Initialize the members taking part in the structure.
For example:
stAddress is Structure
CompanyName is string
ContactName is string
Address is string
PostalCode is string
City is string
Country is string
END
ACustomer is stAddress
ACustomer.CompanyName = "PC SOFT"
ACustomer.ContactName = "Paul Doe"
ACustomer.Address = "3 Rue Puech Villa"
ACustomer.ZipCode = "34000"
ACustomer.City = "Montpellier"
ACustomer.Country = "FRANCE"
Remarks
The structures can be declared: - in the project code (structure global to the entire project).
- in the code of a window or page (structure global to the window or page).
- in any process (structure local to the process).
