Arguments

 

target_invo

   OpenVMS usage:invo_handle
   type:         longword (unsigned)
   access:       read only
   mechanism:    by reference
   The address of a location that contains a handle for the target
   invocation.

   If you do not specify the target_invo argument, or if the handle
   value is 0, an exit unwind is initiated.
 

target_pc

   OpenVMS usage:address
   type:         longword (unsigned)
   access:       read only
   mechanism:    by reference
   The address of a location that contains the address at which
   execution should continue in the target invocation.

   If the target_pc argument is omitted or the value is 0, a system-
   defined target PC is assumed and execution resumes at the
   location specified at the return address for the call frame of
   the target procedure invocation.
 

new_r0

   OpenVMS usage:quadword_unsigned
   type:         quadword (unsigned)
   access:       read only
   mechanism:    by reference
   The address of a location that contains the value to place in the
   saved R0 location of the mechanism argument vector. The contents
   of this location are then loaded into the processor R0 register
   at the time that execution continues in the target invocation.

   If the new_r0 argument is omitted, the contents of the processor
   R0 register at the time of the call to $GOTO_UNWIND are used.
 

new_r1

   OpenVMS usage:quadword_unsigned
   type:         quadword (unsigned)
   access:       read only
   mechanism:    by reference
   Address of a location that contains the value to place in the
   saved R1 location of the mechanism argument vector. The contents
   of the location are then loaded into the processor R1 register at
   the time that execution continues in the target invocation.

   If the new_r1 argument is omitted, the contents of the processor
   R1 register at the time of the call to $GOTO_UNWIND are used.
