[texhax] checking for upper-case character

[martin f krafft]

Dear list,

In a new command I am defining, I want to determine if the first
letter of one of the arguments is a capital letter, and if so, then
do something slightly different than otherwise. Is this possible?
I tried to search the web and look through existing .sty files, but
I have not found a single clue.

Thanks,
