LISP runs intermittently

[Anonymous]

Hello everyone.

I'm new to the Forums and new to LISP programming. I've written a program to insert fastener hardware into our drawings. It works well on my machine, but sometimes on other machines it places the blocks in what seems to be random locations. We've isolated the issue to workstations (i.e. we all tried the same drawing and switched users to different machines). Does anyone see a problem with the LISP? Since I am very new to programming, any and all additional constructive criticism is welcome.

Thank you in advance,

Doug

A common set of subroutines, written various ways, is:

 (DeFun U_W (p)  (trans p 1 0)))
 (DeFun W_U (p)  (trans p 0 1)))

UCS to World, and back.

Also, using "UCS" "P"

to get to a know Coordinate system

asmay not be as effective using "UCS" "W"

or to  some named corrdinate system.
