NAME

     ops - Perl pragma to restrict unsafe operations when
     compiling



SYNOPSIS
       perl -Mops=:default ...    # only allow reasonably safe operations

       perl -M-ops=system ...     # disable the 'system' opcode




DESCRIPTION
     Since the ops pragma currently has an irreversible global
     effect, it is only of significant practical use with the
     `-M' option on the command line.

     See the the Opcode manpage module for information about
     opcodes, optags, opmasks and important information about
     safety.



SEE ALSO
     Opcode(3), Safe(3), perlrun(3)
