Many thanks Monks (and a bow)- your knowledge of internals is awe-inspiriing, and in my case perhaps a bit of a consolation. For now based on your findings, I'll go with 0 and 1 will be my cast-value from bool to int.

I also tried it with a regex and that ALSO yielded 0 and 1 (yay).

I'd actually considered using ? : construct, and may end up with that, but I'm hoping I don't have to.

Here my issue- I'm sort of allowing web users to *write psuedo-perl* , which I convert into actual Perl, then eval. I want to only yield them a very tiny subset of commands- mostly along the lines of doing math, or setting values on values in only one hash. So I didn't want to let them deviate too far even into conditionals. All of course for obvious security reasons..

Thanks * 10 !

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
