I do know to read C, but not speak!! I did not know that code of core functions are written in C. Now I know. Are there any core functions which are written in Perl (some simpler functions!!).	[reply]

um, sure, see http://perl5.git.perl.org/perl.git/tree/HEAD:/lib, anything from glob to dbmopen to perl -V loads up some perl module to do stuff	[reply]

Perl is written in C. All of the operators ("core functions") are implemented in C. It was said that `glob` was written in Perl, but it's `pp_glob` in `pp_sys.c`. (Sometimes, this does result in Perl getting executed, but not always.) It was said that `dbmopen` was written in Perl, but it's `pp_dbmopen` in `pp_sys.c`. (Granted, this does result in Perl code getting executed.) There are many core and non-core modules written in Perl, but the functions in perlfunc are necessarily written in C.	[reply] [d/l] [select]
