The trouble with -encode- is that it puts the levels in alphabetical order. So in the L, M, H case you would get H = 1, L = 2, M = 3. To get around this you would have to define a label by hand and assign it to the string variable.

True, but as Nick points out you would have the same problem with factor variables. One way or another you have to do a little extra work to get the codes in the order you want if they aren't in that order already.
