Immediately terminate an instruction with a given set of results.

Syntax

@results = "some statement";
RETURN @results;

Ordinarily, the results of an instruction are based on the last statement to execute; RETURN allows you to do this at any point in an instruction. In contrast to EVALUATE (which means “break out of this instruction if the preceding statement returned no results), RETURN breaks unconditionally. With RETURN, you supply the @table whose value should become the results of the instruction.

The instruction exits successfully, with an exit code of 0 if the results have content, and 1 if they have no content.

Take care to ensure the results returned have the same shape as the results returned by other parts of the instructions, as described in SCALE User Guide: Inconsistent branching results.

@reg = NativeServices.RegistryGetValue(
            Hive:"HKLM",
            Subkey:"SOFTWARE\\MyVendor\\MyConfiguration",
            Name:"SecuritySetting");

// If the setting exists, return a message indicating we're secure
IF (@reg)
    @msg = SELECT "System already secure" AS Status;
    RETURN @msg;
ENDIF;

// Otherwise, take some action...
// ... and report that back. No need to use RETURN, because
// this is the last statement in the instruction.
SELECT "System was insecure, but is now secure" AS Status;
