Re: Sorting an array w/multiple fields

I don't have a qsort example, and I will someday build one, but here's an
idea. If the sort order is always left-to-right, I wonder if you could
overlay a large char array, with each elem the size of the DS, and just use
SORTA. I am not sure if the numeric field would sort right, but it's worth a
try.

i.e. if the DS looked like
5A
3P 0
5A

then declare a pointer
pArray * Inz(%Addr(Array))

And a char array
Overlaid 12A Based(pArray)

then just use SORTA on the Overlaid array. Might be worth a try.
