Jon,
I agree with what you're saying. I just have been dealing with vendors that do not publish 100% of the JSON formats and they love to change them without telling anyone. Also a time saving when you're dealing with api with 100's
of fields and you only need a couple values.
The count is cool I have to try that.
The one issue I did not email Scout about is when you have null values. I don't think YAJLINTO handles them.

Subject: Re: data-into
Be VERY VERY cautious about using allowmissing=yes.
In general it is a very bad idea.
Reason is that there is no granularity - anything and EVERYTHING could be missing and DATA-INTO would simply say "Yup - all looks good to me!".
Back in the mists of time with the initial release of XML-INTO allowmissing was all we had - but we now have a better option countprefix. By using countprefix you can tell DATA-INTO exactly which fields are optional and you have an easy way of detecting whether they are present or not.
Using part of your DS as an example:
Dcl-ds billing_address;
name char(40);
street_address char(40);
city char(40);
state char(2);
zip char(10);
End-ds;
Assume that name and street_address are both expected but that the other fields are optional. You could add the option countprefix=count_ and change the definitions to:
Dcl-ds billing_address;
name char(40);
street_address char(40);
count_city int(5);
city char(40);
count_state int(5);
state char(2);
count_zip int(5);
zip char(10);
End-ds;
Now if city, state or zip are omitted, even without allowmissing=yes, no error will be flagged and the relevant count_ fields will be 0 or 1 depending on the absence/presence of the field in question.
You can apply the same thinking to the name and street_address fields too and then test their count_xxxx fields to ensure that they were present and issue your own appropriate error if they were missing.
So - if your mother had known about you using allowmissing=yes she'd have told you to STOP IT before it damages you permanently!

After seeing Scott Klements session at Powerup18 on using Json & the
new data into, I wanted to start using it.
I am getting the error
Message . . . . : The document for the DATA-INTO operation does not
match
the RPG variable; reason code
5.
Cause . . . . . : While parsing a document for the DATA-INTO operation,
the
parser found that the document does not correspond to RPG variable
"result"
and the options do not allow for this. The reason code is 5. The
exact subfield for which the error was detected is
"result.customers(1)".
The
options are "doc=file case=any countprefix=num_". The document name
is /paytrace/889_output.json; *N indicates that the document is not
an externa file. The parser is 'YAJLINTO'. *N indicates that the
parser is a procedure pointer.
So that leads me to believe my DS does not match, but I am not seeing
where it is not matching, unless you need to define fields you are not
even going to use in the pgm.
Here is my DS:
Dcl-ds result qualified;
success ind;
response_code int(3);
status_message varchar(500);
num_customers int(10);
Dcl-ds customers dim(10);
Dcl-ds credit_card;
masked_number char(16);
expiration_month int(2);
expiration_year int(2);
End-ds;
Dcl-ds billing_address;
name char(40);
street_address char(40);
city char(40);
state char(2);
zip char(10);
End-ds;
email char(70);
End-ds;
End-ds;
Here is the raw json I am trying to read from the IFS:
{"success":true,"response_code":1,"status_message":"Your request has
been successfully completed.","customers":[{"customer_id":"100-1
","credit_card":{"masked_number":"************1111","expiration_month"
:12,"expiration_year":20},"shipping_address":{"name":"","street_addres
s":"","street_address2":"","city":"","county":"","state":"","zip":"","
country":"US"},"billing_address":{"name":"Transfer
Order","street_address":"Internal Use
Only","street_address2":"","city":"Anywhere","state":"OH","zip":"44721","country":"US"},"email":"
testing@xxxxxxxxxx","phone":"","fax":"","created":{"at":"5/25/2018
7:26:13
AM","by":"demo123","from_ip":"x.x.x.x"},"discretionary_data":{"Site
IDs":"","Company Name":"","Location":""}}]}
The data-into is:
data-into result %Data(outFile
:'doc=file case=any countprefix=num_')
%PARSER('YAJLINTO');
Anyone see where I am missing what is causing the error?
Thanks!!
