>> string = "\37" # => "\037"

Ruby

Hi.

I want to create a string with the backslash character followed by the
number 37. Whenever I try to do this, ruby always creates “\037” !

e.g. in irb:

string = “\37”
=> “\037”

How can I avoid this? I tried different quoting, escaping, etc.

I am missing something fundamental here :frowning:

Any advice gratefully received.

What different quoting did you try? There are a couple of ways to start
looking at this - if you need to use double quotes then you can escape
the backslash, and if you don’t need to use double quotes then the
number of things the backslash escapes are reduced. You should also be
aware that irb’s result display is different from what you’d see with
puts. For example:

string = ‘\37’
=> “\37”
puts string
\37
=> nil
string = “\37”
=> “\37”
puts string
\37
=> nil

Hope this helps,

Mike
