Alsys provides package unsigned. I The documentation says, in part
"This package provides types that implement unsigned bytes and words and 
related operations" "type BYTE is range 0..255;"
"for BYTE'size use 8;" then they suppress overflow and range
check. "type WORD is range 0..65535;" 
"for WORD'size use 16;" again overflow and range
check is suppressed. This is their 386 compiler which is still
a 286 code generator so it is a 16 bit ccomputer from
an Ada point of view.
   They use unchecked conversion to allow you to convert
a byte to short_integer. If anyone wants to know all of
the functions I suggest that you contact Alsys because
I am concerned that I am approaching the copyright
forbidden zone and don't want a visit from the Alsys
lawyers or the copyright police.
