Hi JB,
Seems I should have read further in the thread. (smile)

Firstly there was a typo in the example - but it also seems I was
wrong. Its
an old habit that perhaps was justified a long time ago?
function countLines someLines
repeat for each line someLine in someLines
add 1 to lineCount
end repeat
return lineCount
end countLines
I do remember having errors in handlers where an a variable that
was first
declared/initiated inside a repeat loop (in this case "lineCount")
would
return the literal text "lineCount' and not empty if the repeat
loop was
never entered into (ie someLines) was empty - maybe it was just in
a version
of the debugger - no idea.
Well one bad old habit fixed :)
Maybe you are thinking of a problem I have had which
was dealt with by declaring the variable just before I
do the repeat line. When I am going to add to a variable
I always make sure it has something to add to first.
put 0 into lineCount
function countLines someLines
repeat for each line someLine in someLines
add 1 to lineCount
end repeat
return lineCount
end countLines
