Hi All,  
I have a string (which contains variable) in a variable

variable\_name = “sample variable”

initial\_string = “#{variable\_name} and the text goes on” (The string  
is being retrieved from Database (as string), so automatic variable  
resolving will not happen)

I need to have

some\_function(initial\_string) -----\> “sample variable and the text  
goes on”

I hope i am clear!

Regards,  
Mohit
