Hi all,

I've got a problem with Plot and Table "non-standard" evaluation.

When I specify list1=Table[Evaluate[function[ksi]],{ksi,1,2,0.01}]

I get 100 numbers that are not the values at ksi 1, 1.01, 1.02,...

The same happens with Plot of the function.

When I type function[1] I get the proper value though. Must be that ksi is
held unevaluated and ends up mangled in my function. (which is a module
that I wrote)

How can I avoid this kind of behavior? I don't quite understand at this
point the various evaluation schemes of Mathematica very well. Any
didactic pointers wellcome.

Thanks, John
