Fwd: questions about MCSim

Hello,

I am a PhD student at Oregon Health & Science University. I am using MCSim to do my modeling work for hormone
profiles in Fathead Minnows. The question I would like to ask is about "vectors". 

According to MCSim manual, vectors should be defined as <variable-name>'['<integer>']'. Can I define
the <integer> as a variable? I mean, for example, I would like to use a 'n' to replace the <integer>; then in
the first run, I define n=10 (the vector has a length of 10), and in the second run I define n=7 (the vector has
a length of 7), as so on. Then, for different runs, the length of the vector varies.

I tried several times, it seems that the present program does not accept it. Would you please give me any
suggestion? Can I modify the program a little bit to add this function in? and how? Thank you very much!

Best!

Cindy
