I am a new coder with live code and we have been giving homework to create a simple program that gets user data and displays it in an output. The 1 thing we have to do though is verify data with IF statements and I am struggling.
I will post show the code below of what I have done so far, I have commented what I would like to do, but I just cannot seem to figure out how to do it.
Code: Select all
//Variables that will be used.
global username, password1, password2, email, gender, dob
on mouseUp
get_user_data
display_result
end mouseUp
on get_user_data
ask "What is your name?"
put it into username
ask "Please enter a password you would like to use."
put it into password1
ask "Please re-enter the same password so we can verify it"
if password1 = password2
then //jump to part in this scirpt
else answer "The passwords you entered did not match, please try again." then
//jump back up to asking for password
end get_user_data

Since this is homework I'm not going to give you a complete answer, just a hint. Look at "command" in the LC dictionary.
Edit: I just realized they still haven't added command to the dictionary, so try "on" which is a synonym.

Hi.
The syntax for doing what you want sort of goes like this:
Code: Select all
if "truth" = 42 then
tellHermann
else
relax
end if
on tellHerman
answer "What gives???"
end tellHerman
on relax
answer "Whew"
end relax
Function and command calls are made by name. This is in contrast to, say Basic, where you might "jump" to a particular location. (Or even a line number. Is this still is use?) Anyway, it is important that you play with this. A lot.

And to add...
I see you put something into username and password1
But there is still one missing.

Recently I searched a developer name, that jacque mentioned. I had about a billion of very similar results, of sort I don't like very much. So I prepared to see pure horror when searching for the "???" that Craig mentioned, because I don't know what "???" is. You won't believe it and I couldn't believe it: NO HITS (in words: zero hits) when searching with Google. Not even Craig's post above was found ...
Craig, who stole the question marks?? (<-- Even these two will not be be found by Google.)
Simon, there is no use in trying to think about sha-42 or asking for his password2, here it is, "???", the one you can even post here, will not be found, just try ...

Sorry, Hermann, those extra "?" are idiomatic for native English speakers, and just mean a really big question.
Like "Yipes!!!!" means 42 = "true".

Hi Craig.
I use this too and as a young man I was even able to remember what question mark number 42 on my third sticky meant. Now only three on one sticky are too much
(Time to go to bed, sorry, it's early morning here, just before the dawn.)

Hi 'smith8867', probably 8/8/67 or 6/7/88 is your birthday, so this is NOT your homework?
Magice, Craig and Simon have sometimes very black british humour (although at least two of them are not from MontyPython).
You could start with the following and come back They all here will help you as they helped me when I was a very beginner (and wasn't able to finish my homework).
Code: Select all
on mouseUp
repeat with j=1 to 4
put get_user_data(j, line 1 of uPasswd) into uPasswd
if line 1 of uPasswd is "Seems to be OK" then
put line 2 of uPasswd into line 1 of uData
exit repeat
else
if j=4 then
answer "Not very funny."
exit mouseUp
end if
end if
end repeat
# .. similar for other data and other lines of uData
put uData into field "safe place"
end mouseUp
function get_user_data nbOfTrials, askStrg
ask askStr & CR & "Please enter a password (trial" && nbOfTrials && "out of maximal four)"
put it into password1
ask "Please re-enter the same password so we can verify it"
put it into password2
-- is not casesensitive, also 2*21 = 1+41 ... Still a lot to do here
if password1 = password2 and passwd1 is not empty then
return "Seems to be OK" & CR & passwd2
else
return "The passwords did not match, please try again."
end if
end get_user_data
Magice, please, how do you know this is his homework? I never had to do such homework, you can conclude this from my script above, I've to do this better as homework now.

Quick shot:
Maybe because Mr. Smith mentioned this fact in his very first sentence?

Yes. He said. But how do you know it *is* his homework?
May be he pretended this only, because this is in fact a non-trivial, difficult question: "How to jump to different areas in the script?" Read 'script' here as 'handler'.
I saw some discussions about that and first thought this is once again one about that. None of these discussions did end in a satisfactory solution/answer.
Have you a special trick in your treasure chest for ' How to jump within one handler to "marks"? '
