DEFAULT SIZE
Syntax:
DEFAULT { LOGICAL | INTEGER | REAL | DOUBLE | COMPLEX } SIZE [:] <integer>
Function:
Specifies the default data size for logical, integer, real, double precision or complex objects. The default size is used when no explicit data size declaration has been made.
These commands are made on the command line or in specification files. They cannot be made after fpt has read and analysed the input code.
If it is not otherwise specified, the default logical size is assumed to be the same as the integer size, and the default double precision size is assumed to be twice the real size.
Data sizes may be changed systematically throughout a program by the commands CHANGE LOGICAL SIZE : n, CHANGE INTEGER SIZE : n etc.
The code may be modified to specify the default data sizes explicitly by the command SPECIFY NUMERIC SIZES.
The *n size specifications may be stripped from the code by the command REMOVE NUMERIC SIZES.
The size specifications may ne changed to KIND specifications by the command CHANGE DATA SIZES TO KINDS.
