First example: The line is read from the file The line is parsed from the first space character to the end of the line The parsed information is compared and the $ifmatch identifier is set/unset the contents of $ifmatch are returned This is faster, than echoing $gettok($read(%file,%line)),2-,32) because mIRC doesn't have to go through those first two steps a second time for the information to be displayed. 2nd example: The variable is set check the variable, if there is information then echo the variable Re-writing your first code and going with the least amount of processing time, probably would get you Code: echo -a $iif($gettok($read(%file,%line),2,32) == asd,$v2) $v2 will return asd if there's a match, but it's faster than using $ifmatch (which has basically been replaced with $v1) since the setting of $v2 does not require mIRC to read and then parse the line before setting the identifier

i do this test

Code:

test {
  window @test
  var %k 10000

  var %tk $ticks
  while (%k) {
    aline @test $ifmatch
    dec %k
  }
  var %t1 $calc($ticks - %tk) 

  aline @test --------------
  var %k 10000

  var %tk $ticks
  while (%k) {
    aline @test %k
    dec %k
  }
  var %t2 $calc($ticks - %tk) 

  aline @test --------------
  var %k 10000

  var %tk $ticks
  while (%k) {
    aline @test $ifmatch
    dec %k
  }
  var %t3 $calc($ticks - %tk) 

  aline @test --------------
  var %k 10000

  var %tk $ticks
  while (%k) {
    aline @test %k
    dec %k
  }
  var %t4 $calc($ticks - %tk) 

  echo -s ifmatch-&gt; %t1 / %t3
  echo -s var-----&gt; %t2 / %t4
}

(i do 2 series for $ifmatch and 2 for the var because during the creation of the window mirc is slow and the first one is slower and in the first test with %k = 100 the time of the first one is always the double of the second one)
and these are the results

Code:

with %k = 10000
ifmatch-&gt; 578 / 547
var-----&gt; 531 / 547
ifmatch-&gt; 593 / 562
var-----&gt; 532 / 547
ifmatch-&gt; 593 / 532
var-----&gt; 547 / 531
ifmatch-&gt; 594 / 562
var-----&gt; 531 / 547

with %k = 100000
ifmatch-&gt; 5656 / 5593
var-----&gt; 5688 / 5563
ifmatch-&gt; 5578 / 5391
var-----&gt; 5375 / 5391

with %k = 1000000
ifmatch-&gt; 56125 / 55640
var-----&gt; 55610 / 56891

it seems that %var is a little faster than $ifmatch but maybe this test is not the best way...

Built-in identifiers (especially ones without parameters) are generally very fast because they usually behave like variables, ie they fetch a certain (ready) value from memory, for example $chan, $nick (NOT $chan() or $nick()), $v1 etc. Any speed difference between $v1 and %var is so small that it shouldn't concern you. /.timerQ 1 0 echo /.timerQ 1 0 $timer(Q).com
