Re: Suggestions for autogenerating function names to wrap the same code?

[Steve Dondley <s@xxxxxxxxxxx>]

OK, this is semi-working. The corresponding perl function is definitely getting called. If I it has a syntax error, STDERR gets output to the screen.

But for whatever reason, I can’t get any output on STDOUT with something as simple as:

sub blah {
    system('echo', 'hi');
}
