It is undocumented and likely to remain so. The "executionContexts" is 
intended only for use within the IDE, though some people are using it 
elsewhere. It is not guaranteed to remain unchanged and it is unsupported.

The line number of the error in the errors list -- see below.

the number are, in order: the line number in the script where the error 
occured, the column (or token) where the error occured (usually 
corresponds to a word) and the parameter that is being manipulated or 
passed, if any. In your example, the error occured on line 573 of the 
script at word or token 10. There is a parameter of "1" being 
manipulated (I think; I've forgotten some of this.)

Right. That is the list you check to find out what error 198 is. Line 
198 of that list gives you an English description of the problem, which 
is, "Factor: error in left operand". Apparently it doesn't like that "1".

They are a lookup list so that Rev's error dialog can contain an 
English-language description for the user. In general, these are only 
for use within the IDE and they occasionally change, so if you plan to 
include the list in a standalone, you should update it if you rebuild 
with a newer engine version.

Hopefully you are only grey now.
