Re: determining if cursor is in last line of a field
What Mark meant was that the formattedText reconfigures the displayed text as if it had hard returns in just the right places. His script uses the formattedText... Anyone remember the "wordWrap" XFCN in HC? I never knew who wrote it.

Hi Richard, The selectedLine counts the number of hard returns.

Re: determining if cursor is in last line of a field
Try this: answer the formattedText of fld "yourField" It wraps unwrapped text with hard returns, and that will give the last line Craig -Original Message- From: Dr. Hawkins To: How to use LiveCode Sent: Wed, Sep 18, 2013 11:23 am Subject: determining if cursor is in last line of a field If selectedLine() is 1, I am in the first line of a field.

Not sure what you mean, "how the field is actually formatted." If you are talking about possibly having empty lines following the last text in the field, then the number of lines of (word 1 to -1 of fld "myField") would work. Compare this value with the number of lines of char 1 to (word 4 of the selectedchunk) of fld "myField" Maybe I don't understand the problem, though. -- Peter Peter M.
