Name the variables block; helpful when there are multiple


This keyword is related to the topics:


Alias: none

Argument(s): STRING

Default: use of last variables parsed


The optional set identifier specification uses the keyword id_variables to input a unique string for use in identifying a particular variables set. A model can then identify the use of this variables set by specifying the same string in its variables_pointer specification.

If the id_variables specification is omitted, a particular variables set will be used by a model only if that model omits specifying a variables_pointer and if the variables set was the last set parsed (or is the only set parsed). In common practice, if only one variables set exists, then id_variables can be safely omitted from the variables specification and variables_pointer can be omitted from the model specification(s), since there is no potential for ambiguity in this case.


For example, a model whose specification contains variables_pointer = 'V1' will use a variables specification containing the set identifier id_variables = 'V1'.
