Some Japanese programming terms

Being a game developer, I follow some Japanese game devs in an effort to up my Japanese. One just posted this sentence.

配列の指標が全部数値とか

-とか  == "or something like that"

 配列の指標 「はいれつのしひょう」　== "array index / index of an array"

全部数値 「ぜんぶすうち」== all numeric

So the meaning is something like:

Array indices all seem to be numeric.

Lots of programming vocab - which is generally something you won't find in textbooks :D I think it's a good idea to find Japanese people who share hobbies or work that you do, then you'll learn the lingo.
