The maximum number of variables in the array.
name

Return value
Reference to the new array if function executed successfully, NULL otherwise.

Further information
This function starts the definition of a variable array. It returns a reference to an array of variables that may be used, for instance, in the definition of constraints. Variables belonging to an array created by this function may stem from any LP-variables previously defined. They may be of different types, and can be positioned in any order. A variable may belong to several arrays, but it is created only once (functions XPRBnewvar or XPRBnewarrvar). If the indicated name is already in use, BCL adds an index to it. If no array name is given, BCL generates a default name starting with AV.
