Description

All local variables and arrays are classified static by default: there is exactly one copy of each datum, and its value is retained between calls. You can also explicitly define variables as static or automatic in a STATIC or AUTOMATIC statement, or in any type statement or IMPLICIT statement.

However, you can still use STATIC to ensure portability, especially with routines that leave a subprogram by some way other than a RETURN.

Also note that:

• Arguments and function values are automatic.

• A STATIC statement and a type statement cannot be combined to make a STATIC type statement. For example, the statement STATIC REAL X does not declare the variable X to be both STATIC and REAL; it declares the variable REALX to be STATIC.
