Emacs, yes, IDLWAVE no.
You want to replace a regular expression
Type
M-x replace-regexp
(in case you don't know what M-x means, type the escape key, then the x key)
The regular expression you want to replace is,
&\$ *$
and you replace with nothing, just leave the replacement blank. The file should automatically have all "$&" strings at end of line replaced.
If you've never read regular expressions that must look pretty confusing. There is a method to the madness. The partial issue is that in regular expression notation, the dollar sign symbol actually means end of line. We have to use \$ to indicate a literal dollar sign. So these are the meanings.
'&' = literal "&"
'\$' = literal "$"
' *' = any number of space characters
'$' = end of line
So it replaces any sequence of "&$" followed by zero or more spaces at the end of line. Thus endeth the lesson.
