counting lines with no CR

[gyroscope]

Hi, I'm going to kick myself here, I know:

I have a field which does not accept returns. On a button click I wish to put the amount of actual lines in the field into a variable.
The problem is if there is more than one line without returns, it still counts the lines as 1 (i.e as 1 wrapped line). I need to know the amount of visible lines in the field.

So my question please:

How to count the actual lines showing in a field

I should know this but I've forgotten, sorry...

Any help appreciated.

The formattedText property of fields will return the contents of a field with hard returns inserted where the field has soft-wraps. So you could write:

get the number of lines of (the formattedText of fld 1)

Excellent, thank you Richard.
