Building H5 scripts without writing them

Building H5 scripts is complicated and time consuming, but since there aren't really any alternatives it ends up being a key part of most M3 projects.

With LoupeCode, we want to make it possible for anyone to build and test H5 scripts using our interactive builder. Select fields, place elements and add a prompt, all within the context of the screen you're working on.

In the video below we select a column and add an input to OIS300, then attach a simple prompt: "Sum the value of the column for all selected rows." A few minutes later we have a working script that does exactly what we expect, on the first try.

We'll have examples of calling M3 APIs from H5 scripts in the same way soon.
