Hi All, I have a script which use a sub routine from other pl file. Here are the the pl two codes.
# test.pl #!/usr/bin/perl use strict; use warnings; print "Hello, World...\n"; my $perl = "a.pl"; $perl->(10,20);
another .pl script.
# add.pl #!/usr/bin/perl use strict; use warnings; print "here\n"; return sub { my ($a , $b) = @_; return 0; };
if i ran the test.pl. it gives error as Can't use string ("a.pl") as a subroutine ref while "strict refs" in use at C:\Users\Sathish\Desktop\T\test.pl line 9. Please tell me what the error says. It would be great if i have an explanation. Thanks
