   Never tried it from Pascal.  Since errno is a CRTL thing, it's not clear   
   to me that it makes any sense to do so, but if you're trying to debug a   
   library called from the Pascal code, maybe.  In any case the following   
   are the notes I made for myself a long time ago:   
      
   Get errno from VMS debugger:   
      
   set image CMA$TIS_SHR   
   set radix hexadecimal   
   call CMA$TIS_ERRNO_GET_ADDR   
   !   
   ! The above returns an address   
   !   
   examine/long/decimal    
   !   
   ! The above returns errno content.   
   ! If errno content is 65535 (EVMSERR == 65535)   
   ! continue your debugging session with right below   
   !   
   call CMA$TIS_VMSERRNO_GET_ADDR   
   !   
   ! The above returns an address   
   !   
   examine/condition
