I'm writing code that reads a columnar data file and uses the titles of the columns and the values in the current line to make the output filename. For instance, a data file like this 
// Alt Mach AOA Beta Cx
 0  1  10  0   0.1

[download]
would have an output filename like alt0_mach1_aoa10.tmp What I'd like to do is allow the user to specify the format for the output filename. Is there a way to read in user input like Data_Altitude$1_Mach$2.out and replace $1 and $2 with values?? Right now I read the user format statement in and then print it back to the screen, but I get exactly what the user typed back ($1, $2 and all). Thanks for you help!
