No troll, just curious. Still...Even presuming the compiler is not phsycic, why can't you have a tag that says "forget what you have seen up to this point", when you have one that says "ignore the rest of the file?"	[reply]

There is such a construct if you use the -x switch: `>perl -x <<END bla bla bla ignored #!perl stuff_to_execute(); __END__ bla bla END` [download] updated: `s/<END/<<END/` "What should it profit a man, if he should win a flame war, yet lose his cool?"	[reply] [d/l] [select]

`b@d #! perl; print 'ignore b@d'; die;` [download] Will do what you want if started as `perl -x your_script.pl` CountZero "If you have four groups working on a compiler, you'll get a 4-pass compiler." - Conway's Law	[reply] [d/l] [select]

~~Hmmm, still requires the addition of code "<<END" before the data.~~ Update: Yeah, I know I was wrong. Joost's solution works.	[reply]

You could probably do that (more or less) using source filters. `use Filter::ignore-until-BEGIN-token; b@d __BEGIN__ print 'ignore b@d'; die;` [download] Now all that has to be done is writing the `Filter::ignore-until-BEGIN-token`-filter. We will leave that as an exercise for the reader. ;-) CountZero "If you have four groups working on a compiler, you'll get a 4-pass compiler." - Conway's Law	[reply] [d/l] [select]

At first glance it seems that this would be something easily accomplished with a source filter. Of course it's entirely possible I'm wrong since you would then be asking it to forget that it loaded the source filter. ___________ Eric Hodges	[reply]

You can easily remove a source filter. The function in Filter::Util::Call for that is `&filter_del`. Filter::Simple has the "terminator" switch you can set. `ihb` See perltoc if you don't know which perldoc to read!	[reply] [d/l]
