 ! 
 !  The sys$get_env_sensors system service will populate the user's buffer
 !  with an array of the following structure. The dimension of the array is
 !  determined by the number of sensors corresponding to the item code by a 
 !  run-time call to sys$get_env_sensors() with a buffer address of zero or 
 !  buffer size of zero. sys$get_env_sensors() will pass the dimensions back 
 !  to the caller so he can allocate buffers to contain the arrays for 
 !  subsequent calls to sys$get_env_sensors() with valid buffer pointers and
 !  sizes.
 !  See [SYS]SYS_GET_ENV_SENSORS.C
