The program name specified after the
on the user interface.
Note
With arrays of an undefined array length, subprograms can process arrays of variable length
as formal parameter. When defining a two-dimensional array as a formal parameter, for
example, the length of the 1st dimension is not specified. However, the comma must be
written.
