## LIMIT Usage

The `LIMIT` statement is used to limit the number of iterations of a processing loop initiated with a `FIND`, `READ`, or `HISTOGRAM` statement.

The limit remains in effect for all subsequent processing loops in the program until it is overridden by another `LIMIT` statement.

The `LIMIT` statement does not apply to individual statements in which a limit is explicitly specified (for example, `FIND (n) ...`).

If the limit is reached, processing stops and a message is displayed; see also the session parameter `LE` which determines the reaction when the limit for the processing loop is exceeded.

If no `LIMIT` statement is specified, the default global limit defined with the Natural profile parameter `LT` during Natural installation will be used.

### Record Counting

To determine whether a processing loop has reached the limit, each record read in the loop is counted against the limit. If the processing loop has reached the limit, the following will apply:

- A record that is rejected because of criteria specified in a `FIND` or `READ` statement `WHERE` clause is not counted against the limit.

- A record that is rejected as a result of an `ACCEPT`/`REJECT` statement is counted against the limit.

## LIMIT Syntax Description

Syntax Element | Description
--- | ---
`LIMIT n` | Limit Specification: The limit `n` must be specified as a numeric constant in the range from `0 - 4294967295` (leading zeros are optional). The processing loop is not entered if the limit is set to zero.

## LIMIT Examples

- Example 1 - LIMIT Statement

- Example 2 - LIMIT Statement (Valid for Two Database Loops)

### Example 1 - LIMIT Statement

    ** Example 'LMTEX1': LIMIT
    ************************************************************************
    DEFINE DATA LOCAL
    1 EMPLOY-VIEW VIEW OF EMPLOYEES
      2 PERSONNEL-ID
      2 NAME
      2 CITY
    END-DEFINE
    *
    LIMIT 4
    *
    READ EMPLOY-VIEW BY NAME STARTING FROM 'BAKER'
      DISPLAY NOTITLE
              NAME PERSONNEL-ID CITY *COUNTER
    END-READ
    *
    END

#### Output of Program LMTEX1:

            NAME         PERSONNEL         CITY            CNT
                            ID
    -------------------- --------- -------------------- -----------

    BAKER                20016700  OAK BROOK                      1
    BAKER                30008042  DERBY                          2
    BALBIN               60000110  BARCELONA                      3
    BALL                 30021845  DERBY                          4

### Example 2 - LIMIT Statement (Valid for Two Database Loops)

    ** Example 'LMTEX2': LIMIT (valid for two database loops)
    ************************************************************************
    DEFINE DATA LOCAL
    1 EMPLOY-VIEW VIEW OF EMPLOYEES
      2 NAME
    END-DEFINE
    *
    LIMIT 3
    *
    FIND EMPLOY-VIEW WITH NAME > 'A'
      READ EMPLOY-VIEW BY NAME STARTING FROM 'BAKER'
        DISPLAY NOTITLE 'CNT(0100)' *COUNTER(0100)
                        'CNT(0110)' *COUNTER(0110)
      END-READ
    END-FIND
    *
    END

#### Output of Program LMTEX2:

     CNT(0100)   CNT(0110)
    ----------- -----------

              1           1
              1           2
              1           3
              2           1
              2           2
              2           3
              3           1
              3           2
              3           3
