Syntax
LENGTH <variable-1> <...variable-n> <$> length <DEFAULT=n>;
Required Arguments
- length
-
can range from 3 to
8 for numeric variables under UNIX. The minimum length that you can
specify for a numeric variable depends on the floating-point format
used by your system. Because most systems use the IEEE floating-point
format, the minimum is 3 bytes.
- DEFAULT=n
-
changes the default
number of bytes that are used for storing the values of newly created
numeric variables from 8 to the value of n.
Under UNIX, n can range from
3 to 8.
