Opening CP/M files (.asm/.bas)

I have an Apple II with a Z80 card, and lots of CP/M disks for it but I'm having a problem opening the .ASM and .BAS files. I thumbed through a book on both Mbasic and CP/M but neither of these books clearly describe how to work with these files. The Mbasic books says to open Mbasic, and at the "OK" prompt type RUN "B:MAINT.BAS" (for example)but when I do that, it gives me a "Direct Statement in file" message, and then it goes back to the "OK" prompt. I don't have a clue how to work with the .ASM files -like SUPRTRK3.ASM or BLKFRI2.ASM. I can see that they are games by typing TYPE SUPRTRK3.ASM but the text flies by so fast that I can't see much else. I have a lot of disks that have nothing but .BAS and .ASM files so any help that you can give me would be appreciated. Also, I have one disk that has a single large file called PILOTA.LST. What do I do with that? Thanks for your help. Ernest
