-
length
-
can range from 3 to 8 bytes for numeric
variables in the OpenVMS on HP Integrity
Servers environment.
-
DEFAULT=n
-
changes the default number of bytes used
for storing the values of newly created numeric variables from 8 to the value
of n.
In the OpenVMS on HP Integrity Servers environment, n can range from 3 to 8
bytes.
The LENGTH statement specifies the number
of bytes used for storing variables.
In general, the length of a variable depends on
-
whether the variable is numeric or
character
-
how the variable was created
-
whether a LENGTH or ATTRIB statement is
present.
Subject to the rules for assigning lengths, lengths
that are assigned with the LENGTH statement can be changed in the ATTRIB statement
and vice
versa.
