statement determines whether to allow normal execution of a procedure or function based on the value of condition. The condition
following the universe command is evaluated. If the condition is true, then the statements following it are executed. If the condition is false, processing stops for the current procedure or user-defined function, and control is passed to the next procedure or user-defined function.
In batch editing mode, if the optional case
keyword is specified and the condition is false, the program will stop processing the case but will still write it to the output file.
