problem with an or statement

[simonbell]

Hi

would someone be able to point out what i might be doing wrong with this little script:

if { $whoisuserhand != "*" } {
set whoisuserinfo [getuser $whoisuserhand INFO]
if { ($whoisuserinfo != "") || ($whoisuserinfo != "*") } {
set whoisinfofile [open $whoisusernick-userinfo.tmp a]
puts $whoisinfofile "Info: $whoisuserinfo"
close $whoisinfofile
}
}

the problem occurs that even if "$whoisuserinfo == *" the rest of the script is still run, even though as far as i can see it should be missing out that part of the script if $whoisuserinfo == "" or "*"

am i missing something?

thanks
Simon

In words you state it like: if $whoisuserinfo == "" or "*", but in code you state it differently.

If "whoisuserinfo == *":

- what will ($whoisuserinfo != "") evaluate too? TRUE or FALSE?

- what will ($whoisuserinfo != "*") evaluate too? TRUE or FALSE?

- And what will { ($whoisuserinfo != "") || ($whoisuserinfo != "*") } evaluate too?
(Read the last statement as: if "this is true" or "that is true" then ... or read it like: if {(*!="") || (*!=*)} then ...)

sorry, my mistake for not being clear enough.

I want to make it so that if $whoisuserinfo returns a value which IS NOT "" (as in blank) or a * then it would execute that particular part of the script.

so in words if $whoisuserinfo returns nothing, or returns a *, i want nothing to happen, but if it contains anything else, i want the script to run.

What you said is fine, all you have to do is turn it into code. The part where you mess up is you're not being detailed in what you say.

Here's what you really mean:

if $whoisuserinfo is not "", AND $whoisuserinfo is not "*", then do this
otherwise do nothing

Another way to say it, closer to what you actually said, is

if $whoisuserinfo is "" OR $whoisuserinfo is "*" then do nothing
otherwise do this

As you can see that logic is kind of backwards. But either one will work.
