There are lots of ways of right-adjusting data within a field.  Here are
a couple of methods.  The second performs the right-adjusting in just
one statement.  But I would guess that the first is faster.  (The second
one requires V3R7.)

-----------------------------------------------------------------------
 1    * "i" is a numeric field.
 1   C     ' '           checkr    field         i
 1   C                   if        i <> %size (field)
 1   C                   eval      field = %subst (field:i+1)
 1   C                                   + %subst (field:1:i)
 1   C                   endif
-----------------------------------------------------------------------

-----------------------------------------------------------------------
 2    * "blanks" is a character field as large as field "field" and
 2    * initialized to all blanks.
 2   C                   eval      field = %subst(blanks:1
 2   C                                 :%len(field)-%len(%trimr(field)))
 2   C                                  + field
-----------------------------------------------------------------------
