Arguments

 

acmode

   OpenVMS usage:access_mode
   type:         longword (unsigned)
   access:       read only
   mechanism:    by value
   Access mode for which the stack pointer is to be adjusted. The
   acmode argument is this longword value. If not specified, the
   default value 0 (kernel access mode) is used.
 

adjust

   OpenVMS usage:word_signed
   type:         word (signed)
   access:       read only
   mechanism:    by value
   Signed adjustment value used to modify the value specified by the
   newadr argument. The adjust argument is a signed longword, which
   is the adjustment value.

   Only the low-order word of this argument is used. The value
   specified by the low-order word is added to or subtracted
   from (depending on the sign) the value specified by the newadr
   argument. The result is loaded into the stack pointer for the
   specified access mode.

   If the adjust argument is not specified or is specified as 0, the
   stack pointer is loaded with the value specified by the newadr
   argument.
 

newadr

   OpenVMS usage:address
   type:         longword (unsigned)
   access:       modify
   mechanism:    by reference
   Value that adjust is to adjust. The newadr argument is the
   address of this longword value.

   The value specified by this argument is both read and written
   by $ADJSTK. The $ADJSTK service reads the value specified and
   adjusts it by the value of the adjust argument (if specified).
   After this adjustment is made, $ADJSTK writes the adjusted value
   back into the longword specified by newadr and then loads the
   stack pointer with the adjusted value.

   If the value specified by newadr is 0, the current value of the
   stack pointer is adjusted by the value specified by adjust. This
   new value is then written back into newadr, and the stack pointer
   is modified.
