As I work ZIL support into Blorbtools, I came up with a question on how uppercase and lowercase are used in that language. I’ve divined that resources are described like this, looking at the source of Shogun:
<CONSTANT P-TITLE 1>
<CONSTANT P-BORDER-LOC 2>
<CONSTANT P-BORDER 3>
<CONSTANT P-BORDER2 4>
My question is this: Are these constant names required to be uppercase or not?
From the MDL docs:
MDL accepts and distinguishes between upper and lower case. All “built-in functions” must be referenced in upper case.
ZILF honors this, although it’s configurable, and it may change in the future. If you’re generating ZIL code, you should generate it in uppercase.
I see. I’ll make those constants declared in the blurb file uppercase later on. In the meantime, I’ve pushed some somewhat significant changes to https://gitlab.com/DavidGriffith/blorbtools
up until now, in the “Ultimate test suite” 
I have found lowercase only in the strings…
