SOAP Message Payload search in ABAP using HANA Fulltext index

I was initially planning to use Elasticsearch for this but, as it turned out, using a fulltext index on HANA was quicker to implement and simpler and, besides, introducing another service in the landscape at the site at which I am working could prove difficult or impossible.

Little Logo interpreter in 81 lines of Red

I have made a little “port” of a logo interpreter I wrote in Rebol some time ago. Back then I did it to try and understand how parsing works in Rebol. Now I just wanted to have some fun with Red, since it has a GUI as of the 0.6 release.

Yet another ABAP JSON parser – and some other stuff
