No difference.

Suppose the last item is determined by some string variable. The result of ALINES() will differ depending on whether or not the variable is empty.
lcC = "a" + ccCRLF + "b" + ccCRLF + "c" + ccCRLF + lcSomeVar
This is troublesome, also because the resulting array is redimensioned even if was originally longer. Do something like
dimension laLine[4]
laLine = ''
alines( laLine, lcC )
? alen( laLine )
The array will shrink back to 3 elements if the last line in lcC is empty.

Constructive frustration is the breeding ground of genius.
If there’s no willingness to moderate for the sake of good debate, then I have no willingness to debate at all.
