Arrays in Rev are like dictionary / shelf / hash / associative arrays 
in other languages. If you need a sequential data structure I would 
recommend using a chunk expression, like a newline separated list (this 
is just my personal preference) instead of an array.

AFAIK you cannot do real integer indexing of items in Rev arrays. Your 
an integer index is converted to a string and used as the key. 
Consequently there is no insert or append function for arrays.

Chunk expressions are really convenient. This kind of thing

put tItem & comma after tList
put the number of items into tCount -- itemDelimiter is comma by default
put item 3 of tList into tLookup

Bugzilla it as a docs problem! Here are a couple of starting points 
though

1) All Documentation By Category | Values & Properties | containers, 
variables and sources of value | (scroll 40% down) Array Variables. **

2) Transcript Dictionary, [] keyword

** If you do bugzilla it, also add a comment this topic doesn't exist: 
"For more information about array variables, see the topic ``About 
arrays and matrixes.`` "  Thanks :-)
