Array Processing Published by: John Dowling on 01 Mar 2013 view comments(4)

I have a field in a customer master that contains both City and state. I want to move state to another field. My thought process is to load the address into an array, read from the last postion untill I find the first no blank field, read one more then I have the state. here is the code

D                 ds
D    address                    30    dim(1)
D      cycyst                   30    overlay(Address)

                    x       = 30;
               dou address(x)<> ' ';
                    x       = x-1;
               enddo;
                    x       = x-1;

                    field6 = %subst(Cucyst:x:2);

I am getting a subscript out of range on the second pass (when x=29)

any ideas ?

thanks

X + 2 = 31, your field is "only" 30.

Here's a routine I wrote for you that should work fine. NOTE: The JOBLOG function from COZTOOLS is not necessary to make it work--its just there to allow you to see the results in the JOBLOG.

     H BNDDIR('COZTOOLS/RPGFREE') DFTACTGRP(*NO)             
      /include cozTools/qcpysrc,joblog                       
     D addr            s             30A   Inz('Chicago, IL')
     D state           s             30A                     
     D len             s             10I 0                   
     D x               s             10I 0                   
     C                   move      *ON           *INLR       
      /free                                                  
           len = %len(%trimR(addr));                         
           for x = len DOWNTO 1;                             
              if %subst(addr:x:1) = ' ' or                   
                 %subst(addr:x:1) = ',';                     
                 state = %trim(%subst(addr:x) : ', ');       
                 leave;                                      
              endif;                                         
           endfor;                                           
           if (state = '');  // Didn't find the state!       
              joblog('Sorry, no State in %s': addr);         
           else;
              joblog('STATE=%s': state);
           endif;                       
      /end-free

Isn't the simplest solution something along the lines of:

EVALR State = %trimr(CityState);

Assuming that the CityState field ALWAYS contains the state as last two characters. Obviously this approach isn't foolproof, if the CityState content cannot be guaranteed.
