How do I assign a pattern to a variable after a match is found using a regular expression in PERL?
For example using a regular expression (RE) and matching as given
I want to assign the pattern matched by the RE to a variable.
e.g. given the input sentence
The value 23,300 should be assigned to a variable (e.g., VALUE).
Any help is appreciated. Thanks in advance.

The subroutine compiles a string into an internal form suitable for pattern matching. The subroutine checks the argument string against
the last string passed to
The subroutine returns 0 if the string s was compiled successfully; otherwise a string containing an error message is returned. If is
passed 0 or a null string, it returns without changing the currently compiled regular expression.
The subroutine returns 1 if the string s matches the last compiled regular expression, 0 if the string s failed to match the last compiled
regular expression, and -1 if the compiled regular expression was invalid (indicating an internal error).
The strings passed to both and may have trailing or embedded newline characters; they are terminated by nulls. The regular expressions
recognized are described in the manual entry for given the above difference.
