My Code snippet below with json as read from file.
What am I doing wrong? How do I access the fields?
My task is to parse the file and create the order in the PxPlus application order file.

  OPEN (HFN,ISZ=10240)"/hit/temp/000000034.json"
  READ RECORD (LFO,ERR=*NEXT)TEMPJSONORDER$;
  LET JSONORDER$+=TEMPJSONORDER$;
  GOTO *SAME
!
  ESCAPE !
  DIM LOAD MORDER${ALL}=JSONORDER$
!
  PRINT MORDER$["Order ID"]
! This  returns nothing at all

I just worked out most of this.....I make a mistake
I defined the JSON in the program as MORDER$["Order ID"]=""  etc....
then B$=DIM(LIST EDIT MORDER${all})

DIM LOAD MORDER${all}... should have been DIM LOAD B${all}...
Now
PRINT b$["Order ID"] returns 000000034

My remaining question is how to loop through the Products
There is no field containing the number of product lines EG ["Product lines"]

What would be the correct syntax to loop through the products given that any indeterminate loop will generate an error?

[Thomas Bock]

The products element is an array, because of "[...]".
So you should be able to address the elements with b$["Products.1.Price"] and b$["Products.2.Price"]
Of course a preceding information of how many item lines are contained would be nice. Without that information best thing you can do is to stop on b$["Products."+str(i)+".Qty"]=$$.

Hi Thomas,
I wrote a loop as you described and it will loop for as long as the upper range you give it without error.
You comment is what I thought.
I guess if the field is null as opposed to blank or 0 then its at the end.
Thanks
