RE: Array over fields in a data structure

The other way to do this without pointers would be:

fTESTDS1   if   e             disk                       
d OneRec          ds                  Qualified          
d   MyFec                        3                       
d   MyFecOk                      1                       
                                                         
d MapDS         e ds                  ExtName(TESTDS)    
d                                     Qualified          
d   MyArray                           LikeDs(OneRec)     
d                                     Dim(8)             
d                                     Overlay(MapDS)     
d Count           s             10u 0 Inz(0)             
 /Free                                                   

    DoU 0 = 1;                                           
      Read TestDS1;                                      
      If %Eof(TestDS1);                                  
        Leave;                                           
      EndIf;                                             
      Count += 1;                                        
      MapDS.MyArray(Count).MyFec = XXFec;
      MapDS.MyArray(Count).MyFecOk = '?';  
    EndDo;                                 
    *InLR = *On;                           
    Return;
                                
  /End-Free                                                 

Demonstrates nice use of nested arrays and mapping fields to data structures. I 
love qualified data structures.
I compiled and test code.

Subject: Array over fields in a data structure


If I have a PF (use it as data structure only) that contains the following like 
below:
     A          R TESTDSFMT        
     A            MYFEC1         3 
     A            MYFEC1OK       1 
     A            MYFEC2         3 
     A            MYFEC2OK       1 
     A            MYFEC3         3 
     A            MYFEC3OK       1 
     A            MYFEC4         3 
     A            MYFEC4OK       1 
     A            MYFEC5         3 
     A            MYFEC5OK       1 
     A            MYFEC6         3 
     A            MYFEC6OK       1 
     A            MYFEC7         3 
     A            MYFEC7OK       1 
     A            MYFEC8         3 
     A            MYFEC8OK       1 

And I've a INPUT file that contain a field XXFEC
     A          R INPUTFMT        
     A            XXCUST         9 
     A            XXFEC          3 
     A          K XXCUST   

If the program needs to loop thru this input file for a XXCUST to load XXFEC to 
fields MYFEC1 to MYFEC8, what would be the easiest way to do this?  I'm going 
blank here.
 
thanks
