# g (group extract) processing code

The g processing code extracts one or
more groups of contiguous character substrings delimited by the specified
character.

| System Processors | Select, Update, List |
| --- | --- |
| Code Type | Attribute Defining |
| Dictionary Attributes | Input Conversion, Output Conversion, Correlative |

## Syntax

```
g{skip.segments} delimiter get.segments
```
Note: The implied spaces between the arguments in the syntax
definition are for visual clarity only and are not allowed.

## Parameter(s)

| skip.segments | Specifies the number of delimited groups to skip before performing the extraction. If omitted, zero is assumed, and extraction occurs from the beginning of the value. |
| --- | --- |
| delimiter | Any single printable character excluding integers and these characters: |
| _ | segment mark (SM) |
| ^ | attribute mark (AM) |
| ] | value mark (VM) |
| \ | subvalue mark (SVM) |
| get.segments | Specifies the number of contiguous groups to extract from the value. |

## Example(s)

The example below illustrates
the results obtained from various combinations of the g code if the value being processed was the string:

```
ca*92714*1000
g*1 ca
g0*1 ca
g*3 ca*92714*1000
g1*2 92714*1000
g2*1 1000
g2*2 1000
g3*1 (null)
```
