DO loop through field names ending in a numeric

Hello Experts,

I have a RPGLE question concerning looping though field names instead of having multiple routines with each field name.

Exp.   I have field names FIELD1, FIELD2, FIELD3, etc.   I know in the past(I've been away from AS/400 for years) I would use a DOU loop something like this.

DOU I = 10
FIELD,I      CHAIN    FILE       99

How do I do that in RPGLE?

THanks!!

In your example, it looks like you're chaining with an array element?

Define the field1, field2, field3 etc in a Datastructure and do an overlay with an array

RPGLE.   In the example it should, from what I remember, it places the number at the end of FIELD, so if it is in it's first loop the field name would be FIELD1, then next loop FIELD2, etc.   I wish I had that old code I did.   I'm thinking Murphey is close to what I did, this was in RPGIV a long time ago.

Dcl-Ds FieldDs;                                    
     Field01 Char(10);                               
     Field02 Like(Field01);                          
     Field03 Like(Field01);                          
     Field04 Like(Field01);                          
     Field05 Like(Field01);                          
     Field06 Like(Field01);                          
     Field07 Like(Field01);

     Field10 Like(Field01);                          
     Field   Like(Field01)
