Hi,

When i tried to load the below mentioned code using rb\_load\_file it  
works

def Category(pArg1)  
lvalue = (""" + “CatA” + “”" + pArg1)  
eval “#{lvalue}”  
end

def is(pArg1)  
return “==”" + pArg1 + “”"  
end

i = Category(is(‘CatB’))

But when i changed the line  
i = Category(is(‘CatB’)) to  
i = Category is ‘CatB’ #removing the brackets  
rb\_load\_file crashes. btw i am using borland c++ 6.0

How to solve this problem?

Thanx in advance.

Cheers,  
Saravanan A

Why do you need to remove brackets?

This is basically a set of rules that our client will define. I am  
writing DSL so that it will be easy for our client. When i execute the  
same using ruby.exe it works but with bracket warning. I think  
rb\_load\_file is crashing because of this warning message.

Please help me

when rb\_gv\_set(“VERBOSE”, Qnil)is executed, it works fine. Basically  
this will suppress all the warnings. This is equivalent to “ruby -w”
