[eclipse-clp-users] Problem using probe_sched

I wanted to use eclipse to create a scheduling application and tried
running the examples in the library documentation for the probe_sched/5.
I get the following error:

"number expected in cplex_set_obj_coeff('EPLEX_OSI'(16'9146e48), 0, 1)"

I also get the same error in the program I wrote. Can anyone suggest the
reason for this error.

Best Regards
Riyadh
