Yes and no Herman.  COMMAND does not automatically expand wildcards
before passing them to your program.  But DOS does have two services
you can to accomplish this task.  They can be accessed through Int 21
functions 4Eh and 4Fh.  Look in your compiler documentation first
though- It probably contains a function like 
_dos_findfirst and _dos_findnext to make the job a little easier.  If
not you can find the information you need in "The new Peter Norton
Programmers Guide to the IBM PC & PS/2"  ISBN 1-55615-131-4.  Enjoy!
