FWLIW, My VFP solution, after reading Dragan's, was the same as Walter's except that I used CHRTRAN rather than STRTRAN.

My last APL coding was back in 1984. I've been trying to work out a solution, but I've forgotten too much.
So far all I can come up with is

teststring <-  teststring[< gradeup > teststring]  
bitmap <-  !=\teststring 
result <- bitmap / teststring.

(not sure if I remember exactly how not equal scan works. I "think" (hope) it gives a 1 when the values change.

Of course, if it were real APL it would be in one line


But I think I would be able to understand the real solution when I see it.

(Sorry Craig. I don't have the keyboard to show the proper glyphs for you)
