Thanks for reply. The question is easily solvable if it is in the same file as the perl script. You can use single quotes or backslash to modify the string.
But as I stated in the message, the "$1.12" was in a text file along with other things, say you have a sentence like this in a file: Apple $1.12. You can't modify the file itself. So it's hard to utilize "\" or use single quotes because you have to first read the sentence from a file.
