LISTVX

The check item type LISTVX is the opposite of LISTV. A LISTVX test allows you to provide a variable name that has been defined by your application to contain a list of variable values that are not valid. PARM1 attribute must have the value NE. The PARM2 attribute must be a variable name entered with "%" as the first character.

Here is an example where a LISTVX check in the majors variable class validates major subjects, providing the application has previously defined the listitem variable to contain the value “MATH SCIENCE ENGLISH HISTORY”:

<!doctype dm system>

<varclass name=majors type='CHAR 8'>
  <checkl msg=liba018>
     <checki type=listvx parm1=ne parm2=%listitem>
  </checkl>

The conversion utility generates a LISTVX verification statement in the )PROC section.
