Prerequisite

Synopsis

Global functions are needed to define the input of the flex scanner and to start the bison parser. The input is taken from a string.

Motivation

It is necessary to be able to give a table select command in ASCII. This can be used in a CLI or in the table browser to get a subset of a table or to sort a table.
