I have discovered truly bizarre behavior in C for VAX/VMS. The
command-line arguments are folded to all lowercase. The only way of
preserving case seems to be to enclose arguments in double quotes.
Thus a command like
tr a-z A-Z
won't work.
How does one tell it not to do it? I could find no references to this
in the index of the VMS C manual.

RE: all arguments to a VAX/VMS C program are converted to lower case I think you've discovered truly normal behavior in VMS. All command line arguments are converted to UPPER case by DCL. The C run time routines then convert everything to lower case for your convenience. You already know the answer to your question, just quote the necessary arguments. Isn't a "bug" an instance of a product performing a documented operation incorrectly, rather than simply performing an operation differently than you expect? Now since the latter can be an anoyance, that could be the definition of a bug, but the two are not equivalent!

They have been converted to upper-case before your code ever saw them. Therefore there is nothing you can do in the code to fix it.
