With CP/M 2.2 CCP, the CCP uppercases command lines. Not just filenames -- there really is no way to enter lowercase into the command line.
MBASIC, does NOT convert strings to uppercase. The BDOS does not convert filenames in FCBs at all.
So mbbasic load "fractal.bas"
is different from load "FRACTAL.BAS"
As I only used CP/M 2.2 "in the day", this behaviour is expected.
If you ended up with a filename with lower-case characters, they ended up "difficult" to handle. PIP, for example, converts commands to uppercase, so cannot be used. REN and ERA cannot be used. MBASIC to the rescue. Since MBASIC does NOT change its string arugment, it can be used to delete
kill "lower.fil"
Indeed, any characters can be used:
kill "'.bas"
to remove '.bas
Still, very difficult to deal with files with : or . in the name! (that parsing IS done by mbasic).

I think thats Ok, because PIP is self-handling the filenames - so it does a uppercase on all chars and couldnt find the FRACTAL.pas It also cant find it, when named "right": RunCPM [v5.7] CCP:[CCP-ZCP3.64K] TPA:[64K] B1>a0:PIP LOW.LOW=FRACTAL.pas NO FILE: =FRACTAL.PAS

Initially, when I started writing RunCPM I thought of messing with Upper/Lowercase myself, but then I decided to not do it and interfere minimally (if at all) with the original software. So what you see happening now is what I remember seeing back in the days when I used my AppleII. In my opinion this adds to the "historically correct experience". :)
