After some struggle I have succeeded to get the PHYSOP package (version 1.5)
running with CSL-Reduce. Soon after that, I encountered the problem described
below. In the meanwhile, I found out that the same problem exists with a
PSL-based Reduce running on VAX under VMS, so I conclude it is not a problem
caused by my hacks to get PHYSOP running under CSL-Reduce, but rather a
problem of PHYSOP.

scalop jx,jz;
state ket;
let jz | ket = xxx*ket;
3*jz | ket;
returns:
3*xxx*ket
whereas
3*jx | ket;
returns:
*** a warning that the evaluation was incomplete due to missing rules, and
jx | ket

the factor three has been lost!

Does anybody know about this problem, and is willing to let me know the cure?
