That's how i do. If i had call "perl script.pl", i could insert -C here too. But i don't and in some situations this way is even not possible, AFAIK, for example running script as CGI. My question is: how to call -C (or equivalent) inside of code, cause on first line this is deprecated?

Are you on a Windows system? On other systems, the OS executes the #! line as if it was typed at the prompt. Since the system doesn't do it for you, you'll need to do it for the system.

You could use a batch file. pl2bat will embed the Perl script into a batch file so you don't have to maintain two files.

Alternatively, you could add -CSDA to the file association.

No, i use Linux. Same problem on Debian and Kubuntu From perl 5.10 -C option is not allowed on first line (#!-line). If i still put it, script is terminated with exclamation:

Too late for "-C63" option at ... line 1.

That's whole my problem here.
