## # Description

L codes return the length of a value, or the value if it is within specified criteria. They take the general form:

```
L{{min,}max}
```

where:

**min**specifies that the process is to return an element if its length is greater than or equal to the number**min**.**max**specifies that the process is to return an element if its length is less than or equal to the number**max**.

### # Not

The L code by itself returns the length of an element.

When used with

max, orminandmax, the L code returns the element if it is within the length specified byminand/ormax.

### # Example 1

```
L
```

Assuming a value of ABCDEF, returns the value 6.

### # Example 2

```
L4
```

If JBCEMULATE is set to ROS, L4 is translated as return the value if its length is less than or equal to 4 - the equivalent of L0,4. Assuming a value of ABCDEF, L4 will return null - the value is longer than 4 characters.

If JBCEMULATE is not set to ROS, L4 is translated as return the value if its length is exactly equal to 4 - the equivalent of L4,4. Assuming a value of ABCDEF, L4 will return null - the value is longer than 4 characters.

### # Example 3

```
L4,7
```

L4,7 is translated as return the value if its length is greater than or equal to 4 and less than or equal to 7. Assuming a value of ABCDEF, L4,7 will return ABCDEF
