Re: Data-Into using YAJLINTO question

It should blow up but since you have not shown your RPGOPTS I can only assume that you specified allowextra=yes with the result that RPG will just ignore the extras.

If you really don't know how many you will receive (or the max is too big for an RPG array) then you should use the %Handler option which will eat the data in pieces and there will be no size limit.

Check out https://authory.com/JonParisAndSusanGantner <https://authory.com/JonParisAndSusanGantner> and look for the JSON section - there are examples there and in the XML-INTO articles on using %Handler - it is really quite easy.

Prepare to be deluged by "why don't you use SQL" options - in this case because you have a very simple document it would be quite easy - but DATA-INTO is probably faster and usually (to my mind) easier to understand and therefore more maintainable,

So I have some code that looks like this... my JSON order DS contains 100 elements.

dcl-c YAJLOPTS const ('{"document_name": "order", "value_null": "", +
"number_prefix": "YAJL_" }');

dcl-ds order qualified dim(100);
id varchar(10) inz('');
recordtype varchar(10) inz('');
external_id varchar(8) inz('');
name varchar(40) inz('');
........ more elements

clear order;
monitor;
Data-Into order %data(inStmf:RPGOPTS) %parser('YAJLINTO':YAJLOPTS);
on-error;
// Get Message Text
RcvPgmMsg( Error
: %len(Error)
: 'RCVM0200'
: '*'
: 0
: '*ESCAPE'
: ' '
: 0
: '*SAME'
: QUSEC);

ErrorMsg = %subst(Error.Message:Error.rcvm0200.qmhldrtn00 + 1);
RptLine(ErrorMsg);
status = -1;
return status;
endmon;


What happens when the JSON document contains 100, 200, or more? I guess I assumed there would be an error I could retrieve.

Any ideas??
