NEXT

 The NEXT function returns an integer value  that  indicates  the
 number of bytes that would be allocated for one component of the
 specified type in an unpacked array or if the specified variable
 appeared as the cell in an unpacked array.


 Syntax:

    NEXT( x )


 The parameter 'x' can be a type identifier or variable.

 Cells in an unpacked array are affected by alignment  attributes
 and,  by default, are byte or naturally aligned.  Therefore, the
 size returned includes the actual size of the type or  variable,
 in   addition  to  trailing  space  required  to  ensure  proper
 alignment.
