# Trying commands one at a time

[Programming guides](README.md)

A REPL is an interactive place to enter code and see a result immediately. Earlier values can remain available until you reset or leave the session.

Inside `pliro repl`, these are tool commands, not Pliro grammar:

| REPL command | Purpose |
|---|---|
| `:state` | Show program-scope variables. |
| `:reset` | Clear cumulative source and runtime state. |
| `:help` | Show help. |
| `:quit` | Exit the REPL. |

Finish a multiline condition, loop, or function in the REPL with a blank line.
