SYMDEBUG Directive 

The SYMDEBUG directive causes the compiler to include in the object file
the information needed by a symbolic debugger.

Syntax 

$SYMDEBUG [XDB    ] [ON ]
          [TOOLSET] [OFF]

$SYMDEBUG ON     (or $SYMDEBUG or $SYMDEBUG TOOLSET) the compiler places
                 debug information into the object file for HP Toolset/iX
                 to use.

$SYMDEBUG XDB    (or $SYMDEBUG XDB) the compiler places xdb-specific
ON               information into the object file for xdb to use.

Default               Off; no symbolic debugger information is included
                      in the object file.

Location              The SYMDEBUG directive must appear before any
                      nondirective statements in the program unit,
                      including the program head.

Toggling/ Duration    Symbolic debugging information continues to be
                      generated for all program units until $SYMDEBUG OFF
                      is encountered.


WARNING  The SYMDEBUG directive cannot be used on optimized code.  If the
         SYMDEBUG directive is used with the OPTIMIZE directive, a
         warning is issued and the OPTIMIZE directive is ignored.
