EXIT

Parameters

None

Operation Notes

When you are using MPE/iX you can start another Command Interpreter by running it as a program. To do so, you enter CI.PUB.SYS, or simply CI. If you enter this command more than once, you will create levels of the CI program.

To determine what level of the command interpreter you are in, use the SHOWVAR HPCIDEPTH command. Then, to back out from the CI, enter the EXIT command. If the command interpreter is the root CI, EXIT is equivalent to BYE and ends the session. Otherwise, EXIT returns to the previous process. To go beyond HPCIDEPTH=2 requires process handling (PH) capability. To end a session without backing out of the CI level-by-level with the EXIT command, enter BYE.

Use

This command is available from a job or session. It is not available from a program or in BREAK. Pressing Break has no effect on this command.

Example

The following example shows how to determine what level of the CI you are in, and then, using the EXIT command, to back out to the root CI:

 SHOWVAR HPCIDEPTH
 HPCIDEPTH=2
 EXIT
 SHOWVAR HPCIDEPTH
 HPCIDEPTH=1

To back out from the second level to the first, use the EXIT command. To back out from the session from any level, use the BYE command.
