You can pass structures as arguments in user-defined functions. Simply name the structure as the datatype when defining the argument. Similarly, user-defined functions can return structures. Name the structure as the return type for the function.
You can also define external functions that take structures as arguments.
Revise is an external function that expects a structure as its argument.
lstr_empdata is a declared variable of a structure datatype.
You can call the function as follows:
Revise(lstr_empdata)
Declare the function first
The external function must be declared before you can reference
it in a script.
For more about passing arguments to external functions, see Application Techniques.
