$HP$ LIST
The $HP$ LIST directive turns on or off the inclusion of subsequent source lines in the listing
output.
Syntax
!$HP$ LIST [ON | OFF]
enables the inclusion of source lines in the listing file. OFF disables the inclusion of source lines in the
listing file.
ON
disables the inclusion of source lines in the listing file.OFF
Description and restrictions
The $HP$ LIST directive controls which source lines are output to the listing file. This directive is
effective only when the source files are compiled with the +list option. It may appear anywhere in
the source file.
If the $HP$ LIST OFF directive occurs in a file that is compiled with the +list option, the listing will
contain everything in the source file up through the directive. The $HP$ LIST OFF directive applies
to the rest of the file, or until a $HP$ LIST ON directive is encountered.
Example 33 Example
The $HP$ LISTdirective is especially useful for disabling the listing of include files, as in the
following example:
!$HP$ LIST OFF
INCLUDE ”/my_stuff/some_generic_declarations.h”
!$HP$ LIST ON
For more information
See “Incompatibilities with HP FORTRAN 77” (page 131)for information about the +listoption.
$HP$ OPTIMIZE
The $HP$ OPTIMIZEdirective enables or disables the level of optimization that was specified on
the command line.
Syntax
!$HP$ OPTIMIZE [ON | OFF]
enables the level of optimization specified on the command line. OFF disables the level of optimization
specified on the command line.
ON
disables the level of optimization specified on the command line.OFF
This directive is effective for all program units that follow it in your program. It should therefore be
placed outside and before the program units it is to affect. If you insert this directive inside a
program unit, it will have no effect on that program unit, only on those that follow.
