The following works fine but this results in a 'Too many parameters: $asc' error. Why is it so?

because mIRC uses , as a special character
the characters such as the comma, braces () {} and so on will produce error results of one or another because mIRC is expecting some other info there, $asc(,) makes mIRC think you are supplying more than one parameter in the identifier rather than seeing your request as "the number for the comma character"

If you just want to retrieve the chr value of characters, you can use this code:
//say $asc($?)
Enter any single character in the input dialog, and the chr value will be msg'd to your channel. Only the first character is displayed.

Wasn't there a method to escape those so you could get them displayed without using an input dialog or similar method? I've tried a variety of placements of ! in there and can't get it to work.

What would be the purpose of it being escaped?
Assuming \\, escaped , why put $asc(\\,) when you could just put 44 in place of the lot.
I see no problem with the small level of limitations placed on $asc in this sence, becuase you really just dont need to be evaluating constants, you should just get the value and use it, now if its a dynamic string containing "," then $asc well work fine of course.

why put $asc(\\,) when you could just put 44 in place of the lot. To find out what the $chr is for it. Obviously, if you know the $chr number, you don't need to worry about it. And, yes, I know comma is 44. However, there are times when I have to figure out some of the others that I rarely use $chr for and $asc won't give me an answer. I suppose I could just create a list somewhere and when I come across the need for them, I'd just look on the list, but I like being able to just use //echo -a $asc(N) to get the value for N. And I thought I had seen something on this forum about how to do that. Just don't remember it anymore and wouldn't have any idea what to search for to find it again.

just create a large chr list for reference...
alias crCHR {
var %x = 1
while (%x <= 300) {
write charmap.txt $+(CHR,[,%x,]) = $chr(%x)
inc %x
}
}
basically this will write to file charmap.txt when and only after you have typed /crchr in mIRC go view your subfolder by either typing //run . or //run $mircdir and find the charmap.txt this will it will tell you which $chr number ='s what

I don't think there is any way to not evaluate a literal comma in an identifier. Or at least I couldn't find one. Other than the method above, here is another way:
//set -u %c , | echo -a $asc(%c)
Or you could make a custom identifier:
alias getasc echo -a $asc($1)
/getasc ,
/getasc (

1) No need to go to 300, since the maximum number of ascii characters is 256 (character codes 0 - 255)
There are some codes that will not write properly
examples:$chr(3) - Ctrl +K
$chr(10) - Line feed
$chr(13) - Return/Enter key
Those are one's I run across many times, so I have them memorized. I also have (or had) a chart that showed all of the ascii codes and what they correspond to. I'll see if I can find it, get it scanned, and post it via ImageShack for anyone to reference.

been posted before but heres mine...
alias ascii {
window -Ck0d @ascii-NUMBERS 372 1 265 700
var %f 1
while %f < 257 {
if %f == 2 { echo @ascii-NUMBERS $chr(%f) - alt + 0 $+ %f (CTRL + B) }
elseif %f == 3 { echo @ascii-NUMBERS $chr(%f) - alt + 0 $+ %f (CTRL + K) }
elseif %f == 15 { echo @ascii-NUMBERS $chr(%f) - alt + 0 $+ %f (CTRL + O) }
elseif %f == 022 { echo @ascii-NUMBERS $chr(%f) - alt + 0 $+ %f (CTRL + R) }
elseif %f == 031 { echo @ascii-NUMBERS $chr(%f) - alt + 0 $+ %f (CTRL + U) }
elseif %f == 032 { echo @ascii-NUMBERS $chr(%f) - alt + 0 $+ %f (SPACE) }
elseif %f == 0160 { echo @ascii-NUMBERS $chr(%f) - alt + 0 $+ %f ("HARD SPACE") }
else echo @ascii-NUMBERS $chr(%f) - alt + 0 $+ %f
inc %f
}
}

Not replying to anyone in particular.... 1) I know I could do an ascii table, but I don't want to.  2) I know about doing it as an alias, and that works fine, but it's still a bit of a pain. Anyhow, I was sure I'd seen a way to do it with just $asc before on this forum, but I forget how, now. Oh, well.

Always have this alias loaded: /asc bset -t &asc 1 $$1- | echo -a $qt($1-) = $bvar(&asc,1-) since i often need to know more then one ascii value I never seen a way to do $asc(,) directly though
