Comparing variables

[Beginner]

Hi everyone,
I am working on an code to check for errors, a simplified example is this:

get shell ("echo hello")
put it into h
answer h = "hello"

I am trying to take an error and match it to an appropriate hard coded string so that the program can respond accordingly.
However, it always returns "false" even though the words in the variable inside match.
Can you guys help?

Hi Beginner,
Welcome to the forum

Why are you using "answer" when the "it" variable contains what you want?
As you say "...the words in the variable inside match".

Hi Simon,
I put "answer" because I wanted to check if the variable values match (answer displays "false"), however, that should not be the case as the variable values should match and "answer" should display true

Here is a case where you have to be careful when comparing strings. I leave this to you:

Code: Select all

on mouseUp
   get shell ("echo hello")
   put it into h
   answer h && the length of h && charTonum(the last char of h)
end mouseUp

Oh, I see how I can apply that to my code.
Thanks a lot

Good.

I do not know why a trailing return comes back with the shell request, but it is a good lesson. When something looks like it ought to work but does not, check out invisible culprits.
