curious "go to" behaviour

[Jacques Hausser]

Hello everybody

I have a stack with a group of cards named "KF 0" to "KF 67". These 
names are put in an array for retrieving them in a special order 
depending of other operations. The bit of script to go back to these 
cards was as follow:

if bc > 0 then
         go to cd backcarte[bc]
         delete variable backcarte[bc]
         subtract 1 from bc
end if

It works well for every card except card "KF 0" for which it stubbornly 
refuses to go there. I turned the problem by:

if bc > 0 then
         if backcarte[bc] = "KF 0" then
                go to cd "KF 0"
         else
                go to cd backcarte[bc]
         end if
         delete variable backcarte[bc]
         subtract 1 from bc
end if

... and it works! Other scripts of this stack use card names in 
variables (including "KF 0") without problems. It's not a question of 
life and death, but I'm puzzled...

Thank you for any hint!

Jacques
