# JSON-Related System Variables

This document covers the following topics:

- *PARSE-LEVEL (r) for JSON

- *PARSE-INDEX (r) for JSON

- *PARSE-TYPE (r) for JSON

The system variables, which are available when using the `PARSE JSON` statement, are only valid in the context of the current loop.

## *PARSE-LEVEL (r) for JSON

Format/length: | I4
Content modifiable: | No

This system variable contains the level of currently nested elements.

`(r)` notation after `*PARSE-LEVEL` is used to indicate the statement label or source-code line number of the `PARSE JSON` statement. If `(r)` is not specified, `*PARSE-LEVEL` represents the level where the parser in the currently active processing loop is working at.

## *PARSE-INDEX (r) for JSON

Format/length: | I4
Content modifiable: | No

This system variable contains the index of currently nested elements.

`(r)` notation after `*PARSE-LEVEL` is used to indicate the statement label or source-code line number of the `PARSE JSON` statement. If `(r)` is not specified, `*PARSE-INDEX` represents the index of the array element where the parser in the currently active processing loop is working at.

Note
System variable `*PARSE-INDEX` is only applicable to array elements and is specific to the `PARSE JSON` statement.

## *PARSE-TYPE (r) for JSON

Format/length: | A1
Content modifiable: | No

This Natural system variable is automatically created for each `PARSE JSON` statement issued.

This system variable contains the type of the delivered data.

`(r)` notation after `*PARSE-TYPE` is used to indicate the statement label or source-code line number of the `PARSE JSON` statement. If `(r)` is not specified, `*PARSE-TYPE` represents the type of the delivered data in the currently active processing loop.

Possible values for ASCII-based systems are:

< | Start of an Object Data-Structure
> | End of an Object Data-Structure
( | Start of an Array Data-Structure
) | End of an Array Data-Structure
A | String type Data-Element
I | Numeric type Data-Element
N | Null type Data-Element
L | Boolean type Data-Element
K | Key (or) Data-Name
