Hi, while testing a program, I erroneously declared the same variable twice within a block, the first time with "my", the second time with "our": { my $fz = 'VTX_Link'; .... ( around 200 lines of code, all in the same block) our $fz = 'VTX_Linkset'; ... } So the initial contents of the $fz declared with "my" is lost, because "our" creates a lexical alias for the global $fz, thus overwriting the previous "my" declaration. It was my error, no question. But I wonder why Perl doesn't mention this - even with "use s...

Hi i found the following explaination: In Ada, "in" parameters are similar to C++ const parameters. They are effectively read-only within the scope of the called subprogram. Ada "in out" parameters have a reliable initial value (that passed in from the calling subprogram) and may be modified within the scope of the called procedure. Ada "out" parameters have no reliable initial value, but are expected to be assigned a value within the called procedure. What does "have no reliable initial value" mean when considering the "out" parameter? By c...
