Greetings... Novice Perl person here... I need to perform a few string manipulations involving environment variables... basically first I need to evaluate that a string contains a variable positioned bewtween $ delimeters. I then need to substitute the actual value of the variable into the string to replace the variable in the string... in a nutshell, I have to convert: string myfile$BASE_ID$.xxx to myfile5.21.xxx or myfile$REVISION_ID$.xxx to myfile77N-13.xxx where BASE_ID and REVISION_ID are environment variables. thanks for any help...
