Find oddity?

Interesting, but I did not mean to cloud the issue. I was just fooling around,


So you do see that, with a single instance of text in a field, successive find commands will alternately box and then unbox the foundtext?


To me, this is a bug.

Hi Craig,

Basically confirmed in 5.0.2 but after a little further investigation I've
discovered this is a feature, not a bug.

I added 2 fields to a new stack, one for the text, the other to display
which loop of the repeat I was in - handler below:

on mouseUp
   put empty into fld "Field2" --loop readout field
   repeat with x = 1 to 5
      find "oddity"
      put x & "," after fld "Field2"
      wait 60
   end repeat
end mouseUp

For only 1 instance of the word to be found, it was as you say, the
displayed blinked, but for multiple instances it sort of worked, and then
didn't, I thought it was random until I discovered that when ever the Find
got to the end of the text it sort of missed a beat before it started again.

So to clarify, in 5.0.2 on my machine, on a single card, with multiple
fields, the Find command sequentially finds all instances of the text, and
boxes all of them, but once at the last instance if the Find command is
issued again, the Box is removed and no find occurs, if you then issue the
Find command again it starts at the beginning. Looking at the Dictionary
this is sort of explained. I believe this is similar to other software I
use which typically comes up with a dialog to say you've reached the end of
the document do you want to start again. With the Find command you could
test for "not found", the result of the find command is empty if it finds
the text, otherwise it returns "not found", at which point you present a
dialogue asking if you want to start at the beginning.
