id_variables

Name the variables block; helpful when there are multiple

## Topics

This keyword is related to the topics:

- block_identifier

## Specification

Alias: none

Argument(s): STRING

Default: use of last variables parsed

## Description

The optional `id_variables` keyword accepts a string that uniquely identifies this variables block. A model can then use these variables by specifying the same string in its `variables_pointer` specification.

Default Behavior

If the `id_variables` specification is omitted, a particular variables specification will be used by a model only if that model does not include an `variables_pointer` and the variables block was the last (or only) one parsed.

Usage Tips

- It is a best practice to always use explicit variables IDs and pointers to avoid confusion.
- If only one variables block exists, then `id_variables` can be safely omitted from the variables block (and `variables_pointer` omitted from the model specification(s)), since there is no ambiguity.

## Examples

For example, a model specification including

    model
      variables_pointer = 'V1'

will link to a response set with

      id_variables = 'V1'
