Create a new table

A table file can be created on disk using the routine TBTINI (TCTINI). This routine defines the size of the file as well as the physical organisation of the table . The size of the file is defined by the number of rows and the number of words per row. Tables are physically stored on disk in two formats: by records, corresponding to the natural way of storing the rows sequentially, and transposed, where all the values of a single variable - a column - are stored together. The routine returns the file identifier .
