Section 3
BDOS Function Calls
This section describes each CP/M 3 system function, including the parameters a
program must pass when calling the function, and the values the function returns to
the program. The functions are arranged numerically for easy reference. You should
be familiar with the BDOS calling conventions and other concepts presented in Section.,
before referencing this section.
BDOS FUNCTION 0: SYSTEM RESET
Entry Parameters:
Register C: 00H
The System Reset function terminates the calling program and returns control to
the CCP via a warm start sequence (see Section 1.3.2). Calling this function has the
same effect as a 'ump to location 0000H of Page Zero.
Note that the disk subsystem is not reset by System Reset under CP/M 3. The
calling program can pass a return code to the CCP by calling Function 108, Get/Set
Program Return Code, prior to making a System Reset call or jumping to location
0000H.
