What line is it?

[RossG]

I have a list field with two items per line..

17 18
22 19
13 21
27 26

I can find the line which item 2 matches
e.g 21 but I then need the line number so that I
can extract item 1 for that line and 3 or 4
lines before and after.

Here's what I came up with.

Code: Select all

local tSearch
   ask "Number to find?"
   put it into tSearch
   set the itemdelimiter to space
   repeat with x = 1 to the number of lines in fld "Your Field"
      if (item 2 of line x of fld "Your Field" = tSearch) then
         answer (tSearch && "is in line" && x &"."&cr&"Item 1 of line"&&x&&" is" && item 1 of line x of fld "Your Field") 
      end if
  end repeat

Thanks for your help ClipArtGuy.

I must remember to use the field and
not the array which populates it (and
is superfluous anyway).

The lineOffset function might be easier, but keep in mind that it will return only the first instance it finds unless you add the second "skip" parameter. Since you want the second item, search for space and the number.

Code: Select all

put lineOffset(space & tNum, fld x) into tLine 

That will give you the line number, which you can use to extract word 2, and then add 1 sequentially to get the next 2 lines.

What everyone said.

And especially Jacque's comment about the first instance. You ought to write a general purpose handler that extracts all the foundLines in any given search, as well as foundChunk within each. I have been using one forever, and find it an invaluable general purpose gadget that I call from a library stack.

Anyone remember Rinaldi's "fullFind"?
