Hi All

The @match function in v5 is crap!

I have a list which contains both mix & x, mix occurs first. If I use @match to find x it always finds mix instead(because it contains x). I want an exact match so wrote my own function to do it...

Code:

:exMatch
rem %1 = list to search
rem %2 = string to find
list seek,%1,0
repeat
    if @equal(@next(%1),%2)
        %x = @pred(@index(%1))
    end
until @not(@ok())%x
exit %x


Is there a better/faster way to do it? I concerned about the overhead of looping through the list each time.

Kind regards

David

I would continue to use the match function (in a loop) but reject results where the length of the string is greater than 1.

Still sucks, but should be faster than looping every line item.
