Thanks,
That does the trick. I was sorting a list and my own function concoction workaround was a lot slower.

Well, that's a bug. A work-around is to call ordergreatp or orderlessp
for which all Maxima expressions are comparable.
e.g. ordergreatp("John", "Barry") => true.
The function "sort" orders stuff according to orderlessp by default.
Should be easy to make strings comparable by < <= >= and > .
(Already = # equal and notequal are OK.)
