You may find some useful data in this book:
Baecker, R.M. and A. Marcus (1990). Human Factors and Typography for More Readable Programs. Reading, MA, Addison-Wesley Publishing Co. (ACM Press).
...
Also, Green cites Payne et al. as showing that a simple but hard-to-use command language was easier to use when commands were in upper case, argument strings in lower case.
