Again I recommend reading the book "SQL/400 Developer's Guide" by Paul
Conte and Mike Cravitz.

Sample code from that book:

     C/Exec SQL
     C+                  Update  Customer
     C+                    Set   Discount = :NewDisc
     C+                    Where Shipcity = :SlcCusCity
     C/End-Exec
     C                   Select
     C                     When    SQLStt = '00000'
     C                       Exsr  ProcessRow
     C                     When    SQLStt = '02000'
     C                       Exsr  SQLNoRow
     C                     When    %Subst( SQLStt : 1 : 2 ) = '01'
     C                       Exsr  SQLWarning
     C                     Other
     C                       Exsr  SQLError
     C                   EndSl

This was written in V4R5.  I would have used free format :-)
Also using constants for stuff like '00000' can enhance readability.
