RE: How to move string value to right?

Suresh,

Hans' answer is one of the good ones, however, it only works on V3R7 and 
later. What I'd like to see the new  EVALR  operation code. Currently, it 
is too cumbersome to deal with all that substring stuff in RPG IV to 
move-right-justified. We've traditionally had MOVE and MOVEL, however MOVE 
doesn't have an EVAL equivalent.

In RPG IV, I can easily left-justify a value within any field by simply 
coding:

  C              Eval          CustName = %TrimL(CustName)

This works great!

However this...

  C              Eval           CustName = %TrimR(CustName)

is the functional equivalent to

  C              eval            CustName = CustName


What I would really like to do, in one statement, is to 
move-right-justified to a result.  But until then, using %SST (oops, I mean 
%SUBST) is one of the methods... ;(
