thecommand is returned to the user's virtual storage area; otherwise,
it is at the user'sterminal. A completion code is returned to the user
as a value in the register specified asBy. In the exaaple above, it
would be register10. A completion code of 0 signifies noraal
coapletion. If there is an error, the coapletion code is the binary
value of the nuaeric portion of the error aessage. For instance, the
errormessage D!KCF!045E userid NOT LOGGED ON returns "045" in the By register. The condition code reaains unchanged.
If a CP coamand is to be executed, the instruction acts as ano-ope If
Ry contains a zero, CP is entered. The BEGINcoamand then returns
control to your prograa.
The user can have the response returned in a buffer rather than to his
console. He is entirely responsible for setting up the buffer,
providing the buffer address, andexaaining and processing the returned
response (contents of the buffer). To have the response returned in the
buffer, the user sets up registers as follows:Rx contains the virtual address of the CP console functions command and paraaeters. Rx.1 contains the virtual address of the buffer to receive the
response.
Ry contains the length of the CP console functioncoaaand (up to
132 characters)with an X'40' in the high-order byte.
Ry+1 contains the length of the response buffer (a positive nuaber
not greater than 8192).
Neither Rx norBy can be register 15; Bx and Ry cannot be consecutive
registers.When returned in a buffer, the DIAGNOSE code X'08' output will also have
