Swap word function

[ssikmace]

I need to create a function that will swap the values for two string variables given as the paramaters for the function. It doesnt seem to hard but i just can't get one to work.

wouldn't you create a temporary variable in the procedure to hold one of the values?

temp:=value1
value1:=value2
value2:=temp

something like that?

Thats what i tried but i couldn't get it to work.

This is what i tried but it argued that the "Left side of Assignment is not a variable"

function swap(word1,word2:string):string
var temp:string
temp:=word1
word1:=word2
word2:=temp
end swap

Ok ive fixed the previous problem so far but now how do i get it to have the switched words as my result, because its giving me "Function failed to give a result"

function swap (var word1, word2 : string) : string
var temp : string
temp := word1

word1 := word2
word2 := temp
end swap

var word1 : string
var word2 : string
get word1
get word2
put swap (word1, word2)

code:

result word1 + " " + word2

?

lol good enough for me, thx. As long as my variables remain switched.

well if you're happy with that, why not just use

code:

function switch(word1,word2:string) :string return word2 + " " + word1 end switch
