# zl(1)

```
NAME
```

**zl** - zenlisp interpreter

```
USAGE
```

**zl \[-L\] \[-bgi\] \[-n nodes\] \[image\]**

```
DESCRIPTION
```

**Zenlisp** is an interpreter for a purely symbolic and applicative dialect of LISP. It may be considered an implementation of pure LISP plus global definitions.

The *zl* command starts the interpreter.

```
OPTIONS
```

**-b** Batch mode. In batch mode, no greeting message is printed, and the interpreter exists in case of an error rather than returning to the read-eval-print loop.

**-g** Verbose GC. Report number of free nodes after each GC.

**-i** Init mode. Init mode is used to build the initial image file. No image is loaded. **Do not use this option.**

**-n nodes** Specify the size of the node pool. Larger pools (up to some limit) increase performance. The memory footprint of the zenlisp workspace is calculated as follows:

nodes \* (sizeof(int) \* 2 + 1)

**-L** Display the terms of use (license) and exit.

If an **image** file name is passed to the *zl* command, the specified image is loaded instead of the default image.

```
