# Abstract

The TIP proposes the addition of a new subcommand to the **array**
command: **value**.  The **value** subcommand would query, reference,
and/or initialize an array element with more options for complexity
than a simple read.

# Rationale

[TIP 215](215.md) proposed modifying the **incr** command to auto-initialize
