Re: inserting spaces with SQL in RPGLE

Is it necessary to use SQL? You might consider the edit code APIs - 
you generate an edit mask that gets applied to a number - this gives 
you the ability to create variable edit words in the same program. I 
says this, as it appears you are leaving space for the currency 
something or other. Building the edit word template for creating the 
edit mask could involve substringing in the same way as i will suggest below.

But if you must use SQL, here goes. I'd go with something with a 
SUBSTRING function. I'd maybe use a table expression to get number, 
then use the result of that in a SUBSTRING function to get the number 
of spaces from a long string of spaces.

with myspc as (SELECT NUMBER FROM DLESTER/RSFILE WHERE CURRENCYISOCD = 'USD')
select char(X_AUTHAXY) concat substring('            ', 1, number) 
concat '-' from yourfile join myspc

Something like this. I have not run it, so cannot guarantee anything.

But the same substring technique can build you an edit mask without 
using SQL - less complex in my view. The APIs are Convert Edit Word 
(QECCVTEW) API and Edit (QECEDT) API - Scott Klement might have 
handled these in his

newsletter, otherwise, it is not too hard to work out how to call 
them - simple calls in this case.
