Yeah, that was me. Only for the sake of being cryptic though, although I'm starting to think we need more code like that these days. Beats 'design patterns'.

*t ^ 0x20 maybe upper

I just had the debugger out, cranking it through.

But it only xors with 0x20 if it's already upper case (or a non-ascii char between 0xC0 and 0xDF) Undeserved 2-vote.

Well, to be honest, I did take a look at the ASCII table.. before that I wasn't sure enough of my answer to post it Undeserved 1-vote.

Copying string, turning upper case into lower case...

[hdjim]

increment the address of s set the value of s to the value of t and increment t. the value of t is dependent on the if statement. AND the value of t with 0x60 and if bit 6 is set, make the value of s = the value of t exclusive ored with 32,otherwise set s to the value of t... then increment the address of t. do this until the value of s is not true.

I used to write my code like this until my boss beat me with stick and took my coffee cup :laugh:

Trying to figure this out, will causes someone to lose more productive than the multi-monitor/multi-tasking debate. ;P

I remember using this technique for an assembly program I wrote many years ago. When I worked out what it was doing, it took a moment to realize why it look familiar... Andreas Mertens

It definitely returns a string with all lowercase characters.

wastes a lot of peoples time on this site ?

This looks like an job interview question, in which case I don't want the job.

[PHLIPH]

Yeah, converts to lower case is right - but don't forget it also does '@' => '`', '[' => '{', '\' => '|', ']' => '}', '^' => '-', and '_' => del. Just felt the need to punctuate it. :)

[neil hudson]

It corrupts strings with @ [ \ ] ^ and _ in them.

I was going to say "Hopefully get someone sacked". Maybe a bit harsh on my part.

It'll change other characters too, such as '@' to '`'!
