How do I substitute the value of a variable if it is found in a string?

mister_t has asked for the wisdom of the Perl Monks concerning the following question:

If the string contains an environment variable delimeted by dollar signs ($). Is there an easy way of detecting, and replacing the variable with its value? For instance. Given that the variable BASE_ID has a value of 5.12 myfile$BASE_ID$.xxx should give me myfile5.12.xxx Thank you for any help.
