Re: Does the eRPG SDK template system support JSON?

This is the best Service program I have used for managing JSON: http://rpgnextgen.com/index.php?content=json
But whether or not COBOL can cope with the pointer based approach I don't know.

I love that you can as easily go to a file as to a CLOB (basically Giovanni builds a buffer and at any point you can grab a pointer to that buffer and the length and use that yourself).

>> No disrespect to Brad's eRPG but some RPG-oriented interfaces can be very difficult to use in COBOL. Reason, in part, is that such routines tend to take advantage of the facilities offered by prototypes - for example the keyword CONST allows you to specify a literal instead of a variable. COBOL has no such option and therefore the fields usually need to be passed exactly as specified in the called routine. That usually requires quite a bit more work and makes the examples hard to follow.

I've seen several tutorial examples of creating JSON in RPG, which is made easier by built-in functions (like trim) and by  the new += assignment operator. Unfortunately, RPG is not a standard language in our shop. So I'd need to use eRPG SDK in ILE COBOL.
