Feels like a very silly question, but it is stumping me.
How do I use 'find' to find '4' when it occurs by itself but not 4
when it
occurs in '4.1', when searching the contents of a field?
I have a field with tab separated values in the form
1 1234
2 2.56
3 4.1
4 9.274
and I want to find only that line in which there is a match of the
inputted
string with the first item. The first item will always be a
unique value.
So I want in some way to do a find on 4 that will pick up only
line 4, and
not the occurrence of 4 in line 3.
Find word doesn't seem to work, because presumably Rev sees the
'.' as a word
limiter. Whereas in fact, its a decimal.... Find string in item
1 doesn't
work either. In fact, none of the parameters on find seem to work.
Peter,
Find is probably not the best choice in this case. I would use the
lineOffset function and look for 4 & tab, like this:
put lineOffset(4 & tab,fld "thevalues") into tLineFound
And I would add to that to precede the number to search for with a CR
just to be on the safe side:
put lineOffset(CR & 4 & tab,CR & fld "thevalues") into tLineFound
This way, suppose you had a series of values where some lines may be
skipped and you want to know if a line *was* skipped; something like:
1 1234
2 2.56
3 4.1
9 8.35
14 9.274
18 20.121
WIthout the "CR" in there, you would match the line starting with 14
if you just looked for ("4" & tab), but you wouldn't match it if you
look for (CR & "4" & tab). Note that it is very important that you
include the preceding CR with the list to find as well, otherwise
your lineoffset will be off. So it can't be:
lineOffset(CR & 4 & tab,fld "thevalues")
but must be
lineOffset(CR & 4 & tab,CR & fld "thevalues")
