Pick up a specified text on several card?

[Jim MacConnell]

Magnus, et.al.,

First, I'm a Revolution Newbie (still assessing Starter Kit) but, as I used
to be a HyperCard nut, I thought I'd chime in at the risk of being
completely off base.

I don't think using Find in a loop like this is doing what one might expect

> put field "sessions" into tempText
> repeat for each line xLine in tempText
> find thisDate
> put the value of foundline() & return after thisLine
> end repeat

What container if FIND looking in? At what point is FIND told to look in
line xLine of temptext? in tempText at all?

My understanding is that FIND looks for matches on cards unless you
specifically tell it to look in a field (which tempText isn't?). In this
case, FIND will keep on checking for thisDate in the entire stack, finding
multiple occurrences.... none of which need have any connection to
"Sessions" or its contents.

For example if field "Sessions" has four lines (even if they are empty),
this loop will find 4 occurrences of thisDate regardless of whether or not
they are in tempText.

Maybe something along the lines would be better
while line Xline of tempText does not contain tempDate
    put xline + 1 into xLine
    end repeat
put line Xline of tempText & return after thisLine


I sincerely hope I haven't missed something obvious and if I've made a
Newbie mistake, I apologize, in advance.
