Hi Ru.
The 'abs' function already exists in Jess. See, for example, the Jess 7.0
documentation:
http://herzberg.ca.sandia.gov/jess/docs/70/functions.html#
"10.12. (abs <numeric-expression>)
Arguments:
One numeric expression
Returns:
Number
Description:
Returns the absolute value of its only argument."

Thank you Win. Indeed, I mean exactly this function, but express myself
not quite correctly, I mean adding CALL to this function. Merry
Christmas and Happy New Year to all!

I think abs function should be added:
(< (abs(- ?xpos1 ?xpos2)) 5)
(< (abs(- ?ypos1 ?ypos2)) 5)
(< (abs(- ?zpos1 ?zpos2)) 5)
