Subject RE: Problem with %udat and references
Date Mon, 16 Apr 2012 12:36:50 GMT
Hi,

Embperl is cleaning up all global variables at the end of the page, so they don't persist
and interfere with the next request.

@tmp is cleaned up, before it gets written to %udat.

If you use "my @tmp " instead it should work, or you can avoid cleaning up @tmp by putting
it's name into %CLEANUP with value 0 (http://perl.apache.org/embperl/pod/doc/Embperl.-page-5-.htm#sect_28)
