Craig,
A way to have the second script working correctly (sum on the counter array =
10) is to declare and fill the counter explicitly before using it; my version:
on mouseup
put "a,b,c,d,e,f,g,h,i,j" into temp
repeat with i = 1 to 10
put 0 into tcount[item i of temp]
end repeat
repeat 10
add 1 to tcount[any item of temp]
end repeat
put "" into fld "F1"
put 0 into tSum
repeat with i = 1 to 10
put item i of temp & " : " & tcount[item i of temp] & return after
fld "F1"
add tcount[item i of temp] to tSum
end repeat
put return & "Sum = " & tSum after fld "F1"
end mouseUp
the sum is always 10 - if you want to go back to craziness, just comment out
the first loop. Sums between 6 and 17 in my trials.
I also noticed that the automatic indent doesn't work correctly for the "repeat
10" loop - perhaps an indication that the interpreter doesn't understand
exactly what we mean…
For Alex: I didn't observe the correcting effect of adding "put counter["b"]
into tJunk" to the loop (OS 10.8.3, either with 6.0.1 or 5.5.4). The result was
as bad as without the command.
A very intriguing bug anyway ! I filled a bug report, # 10925 (giving credit to
Craig for his amazing discovery)
