create new variable using assign variable

I want to create a new variable using assign variable value in r just like a macro using in SAS.

For example:-

ID<-"RC090015"

my_ID_code<-xyz 

It should be written as my_RC090015_code<-xyz.

so my requirement is i want to use ID variable for creating new variable for code generalization purpose. Means suppose i just change the ID variable value so it should be change in all further variable where i used ID variable.

So please help me is there any function in r to include that ID variable for creating new variable including ID value.

Thanks in Advance.
