That isn't "allowed", or all statements in InputPosInt will count
either, maybe I forgot to request "no custom functions allowed"?

Which is why I hate BASIC because I must repeat the variable name.

Right, w/o the possibility of overwriting a file and the file would be
deleted instantly.

$? returns status of last external command (`backtick`, system, pipe
close).
$? & 255 (Euph: and_bits($?, 255)) returns which signal the process
died from, if any.
$? >> 8 (Euph: floor($? / 256); >> is shift right like in C) returns
the errorlevel.

Right if there were an "errorlevel" variable.

Which is why Euphorians need shroud and Perl programmers don't.

I am longing for by-reference argument passing available in most
other languages (BASIC, Pascal, C++).
If that can't be done at least we can be C-like by passing a
pointer.
Pointers aren't ghosts to be afraid of, they work miracles if only
you had them in the first place. Those who do NOT want to use it
can keep their hands off it.

Saves from all that hassle but doesn't tell "hey this is how I work".

Sure.

Correction -- there is no d. f. at all in Perl that I have ever
used or have ever dreamt of, its code is surprisingly cleaner than
Euphoria's end-of-block-anywhere, full-of-english-like-words and
full-of-repetition-of-variable-names. Euphoria beats Perl in its
simplicity in handling sequences and functions, but...

Hmm -- I've warned you it's an advertisement I'm not paid for...
If any of you have ever used `get` on my server, you have executed
at least two perl scripts.
