put lineOffset(cr & "C",cr & tList)
The first cr makes sure the line you're looking for starts with 'C' and the second one is used to 'sync' up the number you're returning.
Definitely a keeper! There are some variations, too, that are worth keeping handy:
## find something at the end of a line
put lineOffset("C"&cr, tList&cr)## find a line which matches on the first item put lineOffset(cr&"C"&comma, cr&tList)
## find a line which matches on the last item put lineOffset(comma&"C"&cr, tList&cr)
If you need a general purpose way to find an item's line, you can still use this:
put (the number of lines in char 1 to offset("C", tList) of tList)
But note that any time you can use one of the above, they will be slightly faster (and have more specific meanings).
Also keep in mind that you can extend this to using the current item or line delimiters.
Here's another interesting one to mull over what it does, just for fun:
replace (the lineDelimiter) with (the itemDelimiter) in tList put (itemOffset(tItem, tList) div itemsPerLine) into tLineNumber if (tLineNumber > 0) then add 1 to tLineNumber
To ponder: why would this be useful for searching data with a fixed number of items per line many times?
