HP Fortran statements
SAVE (statement and attribute)
Chapter 10 457
• Derived type objects
• Records
If the name of a common block appears in save-list , it must be delimited by slashes (for
example, /my_block/); all variables in the named common block are saved. If a common block
is saved in one program unit, it must be saved in all program units (except main) where it
appears.
HP Fortran always saves all common blocks.
The following must not appear in save-list :
• Formal argument names
• Procedure names
• Selected items in a common block
• Variables declared with the AUTOMATIC statement or attribute
• Function results
• Automatic data objects (such as automatic arrays, allocatable arrays, automatic character
strings, and Fortran 90 pointers)
Initializing a variable in a DATA statement or in a type declaration statement implies that the
variable has the SAVE attribute, unless the variable is in a named common block in a block
data subprogram.
A SAVE statement in a main program unit has no effect.
Examples
The SAVE statement in the following example saves the variables a, b, and c, as well as the
variables in the common block dot:
SUBROUTINE matrix
SAVE a, b, c, /dot/
RETURN
The SAVE statement in the next example saves the values of all of the variables in the
subroutine fixit:
SUBROUTINE fixit
SAVE
RETURN
