Sure it did. Just start Microsoft BASIC on CP/M, type a program and save it as "hello". It will appear in the directory as "hello.BAS". Of course the CCP, the
console command processor, will convert all file names to upper case, so you can neither type nor copy nor erase the file, but still it exists. You can even load it from MBASIC using LOAD.
You can have any characters you like in your CP/M file names. Sometimes I ended up with file names consisting of all blanks. I usually used a disk editor to deal with those, but there were lots of more convenient tools for the job.
