Regular Expression Anchors: VBScript.RegExp

What is the difference between

$ (End of Line)

and

\Z (End of String)

with 开发者_StackOverflow社区VBScript.RegExp?

Is it simply that a String can have embedded CR + LF and $ sets the scope to what precedes CR + LF?

Or does it not matter when using VBScript.RegExp since this object does not accept files as input?

Thanks.

It makes a difference depending on your flags. If Multiline is active (/m), $ matches the end of every line (newlines), but \Z only matches the last position on the string.

A string may contain multiple lines regardless of whether or not if came from a file, for example:
"hello world\nfirefox 4 is out"
