$addtok

Adds a token to the end of text but only if it's not already in text.

$addtok(text,token,C)

The C parameter is the ascii value of the character separating the tokens.

Example

echo -ag $addtok(this is a,test,32)

This example will echo this is a test, as it adds test to the end of this is a, seperated by space (ascii-code 32).

var %i = 1
while (%i <= $chan(0)) {
  %channels = $addtok(%channels,$chan(%i),44)
  inc %i
}
echo -ag %channels

This example will echo a list of all channels you are currently on, seperated by commas (ascii-code 44).
