# Dyalog APL′ ("Prime")
"Prime" is intended as a rather minimal modification of [Dyalog APL](https://www.dyalog.com/), but going back and correcting original design mistakes. This mostly regards being primary-axis oriented, but also applies to making the original operators consistent and making `⎕IO←0` forced. The goal is to make APL more appealing to the modern audience. That is, to bring APL into its prime.
Requires Dyalog APL version 17.1 or higher.
### How to use
#### Initialisation
Replacing `ns` with your target namespace (e.g. `#`), do
```
]import ns path/prime
```
#### Running code
Now you have three options:
1. Use the extensions directly with the glyph names.
1. Use `ns.prime.FIX` as a drop in for `⎕FIX`.
1. Use `ns.prime.Repl ''` to start a (limited) self-contained session where the glyphs work. Enter `→` to exit.
1. Use `ns.prime.Repl ref` to start a (limited) session in the namespace `ref`. Enter `→` to exit.
