Graham, could you give a little discussion about Synapse Directives in RebGUI, as I can't find much documentation about them. The wiki just mentions the Synapse Directives: calculator sql-database imaging laboratory However, the following have been added that I have found: no-commas letter assessment injection procedure These Synapse Directives are apparently not case sensitive from what I have seen. I discovered that "letter" inserts the text from a GUI template with carriage returns between each line, which is what I was after (not a long line of text separated by commas or not). Is there any downside to using "letter" in a "regular" GUI, i.e., is "letter" tracked somewhere? Where are the others tracked (i.e, may not be obvious by the title)? How does sql-database work? I see it's usually combined with calculator, but not in the case of "disease" templates like diabetes and PMR.
