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 :)
