because you're not doing it right. The way OR (AND NOR, etc) acts, is that they compare two values around itself and produces a result.

z = "Yes" produces true

"yes" by itself doesnt produce a boolean value so you get an error because OR cant compare two sides.

the proper way of doing it is:
code:

if z="Yes" or z="yes" or z=...

i think a case could be of help here (called a switch in most other languses)

ex.
code:

case z of
   label "Yes", "yes", "YES", "yEs", "yES", "YeS": put "yes was in z"
   label : exit
end case


but i think there may be a fuction that checks to see if it is the same worad but in dif caps wich whould wrok better (or is that just in c/c++?)

most languages have compareStringIgnoreCase function. Well atleast Java does Wink

Turing might have that too. If not, could someone write it and post it in Turing Submitions? Might be useful.

Here's the code for a toUpperCase function...haven't done turing in a while so this might be buggy


code:
function toUpperCase (word:string):string
  var word2 : string := ""
  for i:1..length(word)
    if word (i) >= 'a' and word (i) <= 'z' then
      word2 += chr (ord (word(i)) + 24) %I think it's not 24 but whatever
    else
      word2 += word (i)
    end if
  end for
  return word2
end toUpperCase


All you'd have to do then is say..

code:
if toUpperCase (z) = "YES" then
  put Sys.Exec ("c:\Windows\Shutdown.exe")
end if

umm.... in your code you dont have a 'then' after your if statement

code:
if z = "Yes" or "yes" or "YES" or "yEs" or "yES" or "YeS"
%do whatever
else
exit
end if

is really what you had, this is what you want
code:
if z = "Yes" or "yes" or "YES" or "yEs" or "yES" or "YeS" then
%do whatever
else
exit
end if

Post subject:  Error
code:
if yes = "Yes" or "yes" or "YES" or "yEs" or "yES" or "YeS"
        then
    put " Great! Lets Go! "


everything in quotations is giving me an error, so "yes" in anyform is giving an error, do i have to declare each individual answer as a string?

code:
if yes := "Yes" or "yes" or "YES" or "yEs" or "yES" or "YeS"
        then
    put " Great! Lets Go! "

plz dont screw the poor kid up Mad

you do NOT use := in an if statment Rolling Eyes := will assign a value to the variable, which is stupid. Heck, you can just use
code:

if "yes" = "yes" then
 put "this will always be true
end if


as I said it before, you have to use separate conditional statments.

the proper way:
code:

if answer="yes" or answer="Yes" then
put "you have typed yes"
else
put "you did not type yes"
end if
