System information

1.3 Switching Disks
The operator can switch the currently logged disk by typing the disk drive name, A through P,
followed by a colon when the CCP is waiting for console input. The following sequence of
prompts and commands can occur after the CP/M system is loaded from disk
A:
CP/M VER 2.2
A>DIR List all files on disk A.
A:SAMPLE ASM SAMPLE PRN
A>B: Switch to disk B.
B>DIR *.ASM List all ASM files on B.
B:DUMP ASM FILES ASM
B>A: Switch back to A.
1.4 Built-in Commands
The file and device reference forms described can now be used to fully specify the structure of
the built-in commands. Assume the following abbreviations in the description below:
ufn unambiguous file reference
afn ambiguous file reference
Recall that the CCP always translates lower-case characters to upper-case characters internally.
Thus, lower-case alphabetics are treated as if they are upper-case in command names and file
references.
