can you help me understand the differences in the output of the

given these three filenames: t.txt t1.txt t11.txt

plain findfirst?
"?" means "a single arbitrary character". findfirst with "t?.txt"
should not
match t.txt nor t11.txt either.
yes, i wrote t11.txt when i should have written t1.txt... my bad...
however on
OS/2 native
OS/2 with 4OS2 command interpreter replacement
OS/2 DOS native
OS/2 DOS with 4DOS command interpreter replacement
Vista (32bit)
t?.txt returns both t.txt and t1.txt...
On any DOS based OS (that includes OS/2 and Windows), the "?" wildcard
character will find any character, including no character at all in that
position. So in your example, t?.txt will find t.txt and tx.txt but not
txy.txt. It will not return any filename longer than your search mask,
but return shorter filenames. This is (should be) a functionality of the
underlying system calls.
On *ix based systems, the filenames are evaluated by the shell, not the
OS, and your search result will be different in a lot of cases...
