Re^2: Complex conditional statements

I think that's difficult to understand, even in English.

Guess it's my Russian background and non-linear thinking then. ;)

As for the

if !B then A else if (E and F) then (C and D)
[download]

AFAIK there is no then keyword in Perl, and I wanted to use the corerct syntax (i.e. to be able to replace A, B, C etc by valid statements to get a working code)

By the way, where can I find references to the syntax of those Perl keywords? I tried to search for them, but they aren't functions, and Google promptly omits them from the search criteria...

oh, well, then you're still missing curly braces and mandatory parens :) I was equating to English. But I really meant "spoken language" when I said English... but perhaps that is more of a characterstic of the way English is constructed? I know for me, I had to re-read your original statement a few times to fully grok the meaning. It seems more natural as two separate concepts (personally speaking). Code-wise you want something like (if A, B, C and D were variables): `if ( !$b ) { $a; } elsif ( $e and $f ) { $c and $d; }` [download] if they are statements, something similar should suffice, with perhaps more parens and/or do {} blocks.

You might like to take a look in Tutorials and in particular at Control statements and looping. Perl is Huffman encoded by design.	[reply]

They're "statement modifiers". In general, for help with Perl keywords and such that aren't functions, take a look at szabgab's immensely helpful Perl index.	[reply]

Replace `then` with `&&`. IE `if ( A ) { B }` is the same as `A && B`. Likewise `if ( !A ) { B }` is the same as `A \|\| B`. So to code `if !B then A else if (E and F) then (C and D)` you would say `( ! B ) ? A : ( ( E && F ) && ( C && D ) )` [download]	[reply] [d/l] [select]
