Q:

"String of numbers" vs. "field of numbers"

I'm trying to choose a name for a variable in my program that includes some number tandem.
What is the difference between string and field in this case? For example, which one is better: "field of numbers" or "string of numbers"?

A:

I think it is likely to depend on context. From a scientific or computing viewpoint (given that you have asked about numbers), there is a difference. 
Field is likely to define an area or container in which particular items may be found. A database or spreadsheet may contain a field which may only contain types of data (such as numbers, text, dates etc.) Graphical data may define one of its axes as a field.
String would represent a collection of similar or related items. In computing, a string represents a linear sequence of characters, numbers or other data.
So, you can have both a field of numbers and a string of numbers. What's more, a field of numbers is likely to contain a string of numbers! 
However, if you are asking about general phrase usage, I'd be likely to suggest a string of numbers.
