What is the code for identifying certain words from a text field? (I also want to get the row number)

You can use -> lineoffset that will give you the line number (= row)
Code: Select all
...
put "whatever" into tWord2Search4
put lineoffset(tWord2Search4,fld "the textfield") into tLineNumber
answer tLineNumber
## Will give you the line number with the FIRST occurrence of that word or 0 (Zero),
## if the word is NOT in the text of the field
...

Hi.
Not sure what you mean about "identify". Here is a handler that "identifies" a word in a field 1. In a button script:
Code: Select all
on mouseUp
ask "Find?"
find empty
repeat
find it in fld 1
put the foundChunk & return after temp
if the result = "not found" then exit repeat
end repeat
answer temp
end mouseUp

Hi. Thanks for the code. I would also like a code that gives "TRUE" or "FALSE" depending on whether the certain word is in the text
thanks

That is beautifully simple in LiveCode:
