Re^3: Inherited a perl script...need help (s///)

As I said in the CB, if you only want to replace exact matches (eg: 0300), make sure there isn't a number before or after it:

s/(?!<\d)0300(?!=\d)/9999/g

`s/(?!<\d)0300(?!=\d)/9999/g` [download] should be `s/(?<![0-9])0300(?![0-9])/9999/g` [download] My main point is that both look-behind and look-ahead were using the wrong syntax. My replacement of \d with `[0-9]` is likely not required. - tye	[reply] [d/l] [select]
