Saves an integer to a parameter

    int lr.save_int ( int value, String param_name);

String and Parameter Functions | Java Syntax

## Arguments

Name | Comments
--- | ---
value | The integer value to assign to the parameter.
param_name | The name of the parameter.

The lr.save_int function assigns an integer to a parameter. This function is useful in correlating queries. To determine the value of the parameter, use the lr.eval_int function.

## Return Values

This function returns LR_PASS (0) on success, and LR_FAIL (1) on failure. Note that in many cases, this return value indicates the technical success of the function, and not the result. For example, a function that registers a string to be found in a subsequent step returns LR_PASS to indicate that the registration was successful. This does not indicate that the string was found in the server response.

## Parameterization

You cannot use standard parameterization for any arguments in this function.

## Example

In the following example, lr.save_int assigns the integer 5433 to the parameter ID. This parameter is then used in an output message.

    lr.save_int( 5433, "ID" );
        // ...
    lr.output_message("Get identification number: " + lr.eval_int("<ID>") );
