Product::write : Tag List is Protected Error
Tuhina Singh
I am a newbie to mathematica and I am encountering following error in my first program written in this package.
$Recursion Limit::reclim : Recursion depth of 256 exceeded.
General:: Stop: Further output of $RecursionLimit::reclim would be suppressed during this calculation.
Product::write : Tag List in (...) is protected.
General:: Stop: Further output of Product::write would be suppressed durin g this calculation.
Have spent two days trying to figure it out but unable to resolve this. I tried to use this code at the beginning hoping to resolve but with no success:
Off[Protect::Locked];
Off[Attributes::Locked];
Unprotect[List];
Am using "product" symbol in my program where this error is occurring. Any help would be highly appreciated.
Thanks and Best Regards,
Tuhina

It is hard to guess the reason for the error unless you provide us with the code. Incidentally, I could hardly describe Mathematica as a "package"...

Hello, Tuhina:
OK, my only comment is that, if this is the first program you ever wrote in Mathematica, I think you chose a pretty complicated one.
I'm not familiar with the topic you are dealing with. so it's very hard for me to follow your definitions and try to understand what you're doing.
IMVHO. you should develop some expertise in Mathematica. step by step. before attempting to tackle complicated problems where many different kinds of errors may arise. making the debugging process almost impossible. But I can assure you that the effort can be very rewarding.
Best regards.

avoid confusion, I would not use it to describe Mathematica itself!
Programs are best built up a bit at a time. Assuming your program is
reasonably short, why not post it all - someone will almost certainly
fix it for you.
You should certainly not need to execute Unprotect[List] - this is a
very bad move! I would also avoid using Off until you know why you want
it. In Mathematica, error messages do not stop the code running, so it
is not essential to turn them off - better to leave them there as a
reminder that something is still not right! Also, turning a message off,
does not fix the problem!

I wasn't aware that "package" has a specific meaning in mathematica. Thanks for pointing that out David.
I have posted my code on this link : http://rapidshare.com/files/258720906/ho-lee.nb
Have taken it from a paper on Ho-Lee Model implementation by Markus Leippold and Zvi Wiener.
The first few lines in the code do not form part of original code, its just my (uninformed and bad) effort towards solving the error which obviously didn't work at all... Coupla forums I went thru suggested that the error could be because of some simple error in use of brackets "[" / "{"/"(", but I haven't been able to put my finger on it, hence this post.
Thanks,
Tuhina
