Abstract: vmatch attempts to find records that "match" a given "case" in the sense that they are similar (see rules) with respect to the variables declared in the options. Variable ^casevar^ is assumed to contain a 1 for cases (to be matched) and any other value for non-cases. The new variable ^newvar^ will be created to receive the number of matches for a case and, for non-cases, either the number of times it was called a match or the identification number of the case for which it was first called (see option first). String variables are allowed in the matching process (see option strng).
