@Retention(value=RUNTIME)
 @Target(value={TYPE,METHOD,PARAMETER,FIELD,LOCAL_VARIABLE})
public @interface VARY

VARY - Elastic PL/I type information supplementing base Java classes available for reflection at runtime. Attached to VARYING variables (Java String) defined within procedures (Java methods) or elements (Java String) within groups (sub-classes) to indicate a VARYING CHAR variable. Without it a variable with @CHAR is expected to be fixed length.

Note: Expected to be used in conjunction with the @CHAR representation.

PL/I code


   DCL A CHAR(4) VARYING INIT('HI');
   DCL B CHAR(8) VARYING INIT('THERE');
   A=B;
   PUT SKIP LIST(A);

when compiled is generated as

   @CHAR(len=4) @VARY String a = "hi";
   @CHAR(len=8) @VARY String b = "there";
   EPLI.ByValue(a, b);
   System.out.println(a);

when run displays as
