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

PIC - Elastic PL/I type information supplementing base Java classes available for reflection at runtime. Attached to PIC '9(4)V9(4)' variables (Java Picture) defined within procedures (Java methods) or elements (Java Picture) within groups (sub-classes) to indicate the numeric or character picture definition of the field.

Note: although PIC info of fields is known to the compiler during a compilation unit, Picture variables passed as arguments to procedures in other compilation units with formal parameter definitions PIC(*) allow for restrictions.

PL/I code

   DCL A PIC '999' INIT(123);
   DCL B PIC '9999' INIT(1234);
   A=B;
   PUT SKIP LIST(A);

when compiled is generated as

   @PIC("999") Picture a = new Picture("999",123);
   @PIC("9999") Picture b = new Picture("9999",1234);
   EPLI.ByValue(a,b);
   System.out.println(a);

when run displays as

   234
