Subject: Re: the Regular exp read from file not matching !!

Sorry for the typo error in the earlier mail , I did try "1abcd" on 
/^[0-1]{1}[a-zA-Z]{1,25}$/.  I am putting a regular expression in a file 
and my program picks up this string to do a match with the input an 
string ==> "syntax.match(@newsettings.value)"

here is the debug info for more clarity

(rdb:1) n
setprm_0.1.2.rb:149:            return value
(rdb:1) v l
  filename => "C:\\rubypgm\\Paramsyntax\\prm.102"
  newsettings => "1abcd"
  param => "102"
  syntax => "/^[0-1]{1}[a-zA-Z]{1,25}$/"
  syntaxfile => #<File:C:\rubypgm\Paramsyntax\prm.102>
  value => nil
(rdb:1) l
[144, 153] in setprm_0.1.2.rb
   144            if File.exist?(filename)
   145              File.open(filename,"r+") do |syntaxfile|
   146              syntax = syntaxfile.gets.chomp
   147              newsettings = @newsettings.value
   148              value = syntax.match(newsettings)
=> 149              return value
   150             end
   151            end
   152              return true         # RETURN TRUE IF SYNTAX FILE NOT 
FOUND
   153        end



 thanks
jn
