The SUBMIT command parses the Groovy statements that are between the SUBMIT and ENDSUBMIT commands into a groovy.lang.Script object and calls the Run method on the Script. If one of the LOAD, PARSEONLY, or NORUN options is present, then this command parses the Groovy statements into a Class object but does not run it. Any classes that are defined by the Groovy code are then available for use by PROC GROOVY statements or by Java DATA Step Objects.
