Array population thing I just spotted...
Adrian Williamson
initialize()=
declare
Bob = array of StringObject;
Kate = array of StringObject;
Enddeclare
Begin
Bob[1].Value = ‘I work OK’;
Kate[1].ConcatVarchar(text = ‘I do not – I say E_WT0033 Row 1 is out of range for an array access’);
End;
I just spotted this messing about with JSONObject and the URLConnection class.
A class attribute reference makes me a Stringobject in the array first, but not a method invocation.
It is possible that I have never tried using a Method invocation in a ‘First Assignment’ context in the last 33 years.
Must be all this Python corrupting my mind.

You cannot invoke a method on a non-existing object.
But when you assign an attribute on an array row that has an index of lastrow+1, then a new object is automatically created (and assigned to that row) before assigning the attribute value.
This has been the behavior since the beginning of OpenROAD (Windows/4GL in the late 1980s 😀) .

Or an attribute access on a non existent object – but the array code has a special case for attribute access and does it for you, but not for the method.
The lack of symmetry made me pause, but I did this:
wwwheaders[2].value = '';
wwwheaders[2].ConcatVarchar(text = 'Authorization: Bearer ' ) ;
While I have your attention:
This Curl with the -d daisy chained text:
/*
curl -X POST -H 'Content-Type: application/x-www-form-urlencoded' \
https://login.microsoftonline.com/your_tenant_id/oauth2/token\
-d 'client_id=your_app_client_id' \
-d 'grant_type=client_credentials' \
-d 'resource=wwws://management.azure.com/' \
-d 'client_secret=*******************'
*/
In OpenROAD I got it working like so with ampersands:
PostData.Concatvarchar(text ='&client_id=0af2e49f-73bc-466b-8ca5-6e7b91e251ab' );
PostData.Concatvarchar(text ='&grant_type=client_credentials' );
PostData.Concatvarchar(text ='&resource=https://management.azure.com/' );
PostData.Concatvarchar(text ='&client_secret=2.D8Q~Ml5x_IlB4eK_kFt7VfI3D2y2H8vHZAsaQd' );
//CurExec.Trace(string = PostData);
/* Nope, does not work like the -d shown above
www.SetOption(option = CURLOPT_POSTFIELDS, value = 'client_id=<some garbage>');
www.SetOption(option = CURLOPT_POSTFIELDS, value = 'grant_type= client_credentials ');
www.SetOption(option = CURLOPT_POSTFIELDS, value = 'resource=https://management.azure.com/');
www.SetOption(option = CURLOPT_POSTFIELDS, value = 'client_secret=<more garbage>');
*/
Should I have passed an array of StringObject for that?
I got it working and carried on – but seeing as you are here….

This is expected (and documented) behavior.
You cannot invoke a method on a non-existing object.
But when you assign an attribute on an array row that has an index of lastrow+1, then a new object is automatically created (and assigned to that row) before assigning the attribute value.

The CURLOPT_POSTFIELDS option expects one string (varchar or nvarchar), not an array
(see https://docs.actian.com/openroad/11.2/index.html#page/LangRef/UrlConnection__22option_22_Settings.htm).
The "curl" utility just joins multiple "-d" options together with ampersand as separator.
