This is the help screen that BBBS generates when you enter the REGEXP command 
on the command line:

                             Regular Expression

DESCRIPTION
        Regular  Expression is a standard way to scan for a text. RegExp
        has  specific  syntax  for wildcards which differs from wildcard
        scan used for files. All texts in BBBS are scanned with RegExps,
        the scan in not case sensitive.

        RegExp          What it does
        ================================================================
        foz             text "foz" as it is
        ^               beginning of the line
        $               end of the line
        .               any character
        [foz]           character `f', `o' or `z'
        [^foz]          any other character than `f', `o' or `z'
        [f-j]           equal to command "[fghij]"
        [^f-j]          equal to commnad "[^fghij]"
        (foo|bar)       text "foo" or "bar"
        x?              equal to command "(x|)"
        x+              one or more `x'
        x*              zero or more `x'
        \x              character `x', used finding f.ex. `*'

NOTE
        Following  RegExps  are  valid, but the result might not be what
        you think you asked for.

        RegExp          What it does
        ================================================================
        .*              matches everything
        .               matches everything except an empty line
        fub*            matches lines with "fu"
        file*.*         matches lines with "fil"

EXAMPLE
        RegExp          What it does
        ================================================================
        foobar          scan for text "foobar" anywhere in the line


        ^foobar         scan for a line starting with "foobar"
        fo.bar          scan for a line with text fo<any character>bar
        \*              scan for character "*" anywhere in the line
        foo(bar|ugh)*buz$
                        scan for a line with text "foo" followed by zero
                        or  more "bar" or "ugh" and followed by "buz" at
                        the  end of the line. For example lines "foobuz"
                        and "junkfoobarughbarbuz" matches this RegExp

================

Hope this helps :)

Take care,
Janis
