Hello,
I've created simple procedure in another system, which takes one parameter
(x(1)) as argument function and returns one value.  After compilation,
with 'mex -l fnc.m' command I've created a shared library.
In Mathematica's script I load this function with:

link = Install["f:\\f1.exe"];
F1[0.5] # I have a correct result

Then I define such argument, which are part of a function
fCE=F1[x1]; f
C[{x1_}]=fCE;

and execute the Mathematica function FNC[...,fC,...].

The FNC is defined as follow FNC[...,fC_,...]:=Block[{...,
fCi,...,cog,}
....
bva:=If[cog && Abs[#]>fm, Sign[#]fm, #]&;
fCi:=(++if; bva[N[fC[#]]]ix)&;
...
]
when I try execute such a script I have a error;
Part::partw: Part 1 of {} does not exist...

Any sugestions...
