It's the head of a 'while' loop that counts from the current value of Count up to the number of elements in a string that's a JSON-encoded array (held in a variable called TheDataArray). Each time through the loop it executes a statement, which might be a single command or a block (these use begin...end); here it's a subroutine call; the code assumes Count will be incremented there. (I'm not saying I would actually code like that; it's just an artificial one-liner.) All variables are global but there are rarely more than a few dozen in any one script. The language allows scripts to invoke other scripts and share variables with them; unshared variables remain private.
I originally wrote the compiler and runtime in Java some 20 years ago. Last year I rewrote it in JavaScript as a website coding engine, and I'm now doing a version in Python (as a learning exercise). None of them have ever been widely used by anyone but myself, but that's the fate of most custom languages. The performance is quite good, especially when complicated functionality is wrapped up as script objects (as happens in English). I accept it breaks all sorts of conventions regarding the 'right' way to do things but I'm only interested in what works. Most importantly I can return years later and quickly pick it up again, something I struggle to do even with my own code written in Java or PHP, for example.

"while Count is less than the json count of TheDataArray gosub to AddAnotherRow"
Any chance you could explain what this is checking?
