Bug report for /bin/sh5 under ultrix 4.0

[rouben at math9.math.umbc.edu]

The following short script produces incorrect results under ultrix 4.0:

--------- Begin Script -----------------------
#!/bin/sh5

dummy () {
echo This message from dummy
}

set Hello World

echo $1   # These lines
echo $2   # will echo "Hello World"

dummy

echo $1   # These lines
echo $2   # will echo blanks!! They shouldn't.

---------- End Script ---------------------

Notes:
    /bin/sh5 is ultrix's counterpart of /bin/sh in System V. Probably its 
most significant advantage from a programmer's point of view is its
function defining capability.  In the script above the function "dummy" is
defined to echo a string.  An unintended side-effect of the execution of
the function dummy is that it clears the shell variable $1 and $2.
This shell script executes correctly on Stardent 3000 which is a hybrid
BSD/SysV machine.
