Abc & Mod Identifiers

By Sonny on Nov 08, 2011

The $abc identifier will just return the corresponding position or letter of the English alphabet. Example: $abc(g) ;returns 7 $abc(24) ;returns x $abc(0) ;returns 26 (total letters in alphabet)

The $mod identifier is a simple version of the modulus (%) operator found in many programming and scripting languages. For those not familiar with the modulus operator, it merely takes 2 numbers, divides them and returns the remainder. It's pretty convenient on occasion. Example: $mod(10,2) ;returns 0 $mod(37,7) ;returns 2

Two simple identifiers. If you have any problems, leave a comment and I'll fix/update with what I can.

abc { 
  var %abc a.b.c.d.e.f.g.h.i.j.k.l.m.n.o.p.q.r.s.t.u.v.w.x.y.z r
  return $iif($1 isalpha,$findtok(%abc,$1,46),$iif($1 isnum,$gettok(%abc,$iif($1 == 0,0,$1),46))))
}
mod { var %a = $1, %b = $2, %x = $int($calc(%a / %b)), %y = $calc(%x * %b), %z = $calc(%a - %y) | return %z }

Sonny, mIRC actually supports the modulo operator but yours is slightly better in certain cases since it inadvertently obeys the traditional mathematical definition of modulo (0 <= (a % b) < b, for positive b). $mod(-7, 3) = 2 (correct) but $calc(-7 % 3) = -1.

abc return $calc($asc($lower($1)) - 96)

or:

abc return $and($asc($1), 31)

:p

It doesn't return the full alphabet, but it does return $abc(Letter) as the letter's position and $abc(N) as the Nth number in the alpha bet

abc return $ [ $+ [ $Iif($1 isalpha,pos,mid) ] $+ ] (abcdefghijklmnopqrstuvwxyz,$1,1)
