   type:         longword (unsigned)
   access:       read only
   mechanism:    by reference
   The itmlst argument is the address of a list of item descriptors,
   each of which describes an item of information. The list of item
   descriptors is terminated by a longword of 0.

   The service takes one argument as input, an item list. This item
   list has the following format for a single item descriptor:

   63                31                  0
   +-------------------------------------+
   |  Buffer length   |    Item code     | STENVDEF$L_ITEM_CODE/STENVDEF$L_BUF_LEN
   +-------------------------------------+
   |           Buffer address            | STENVDEF$Q_BUF_ADDR
   +-------------------------------------+
   |       Return length address         | STENVDEF$Q_RET_ADDR
   +-------------------------------------+

   The following table defines the item descriptor fields:

   Descriptor
   Field          Definition

   Item code      A longword indicating which environment variable
                  you want to retrieve. These codes are defined in
                  $STENVDEF.
   Buffer         A longword specifying the length of the buffer
   length         in which GETENV is to write the environment
                  variable's value.
   Buffer         A quadword indicating the address of the buffer
   address        in which GETENV is to write the environment
                  variable's value.
   Return         A quadword indicating the return address in
   length         which to put the length of the value that GETENV
   address        retrieved.
