TYPE B:X.PRNThe file X.PRN from drive B is displayed.
1.4.6 USER Command
Syntax:
USER n
The USER command allows maintenance of separate files in the same directory. In the syntax
line, n is an Integer value in the range 0 to 15. On cold start, the operator is automatically logged
into user area number 0, which is compatible with standard CP/M 1 directories. You can issue
the USER command at any time to move to another logical area within the same directory.
Drives that are logged-in while addressing one user number are automatically active when the
operator moves to another. A user number is simply a prefix that accesses particular directory
entries on the active disks.
The active user number is maintained until changed by a subsequent USER command, or until a
cold start when user 0 is again assumed.
1.5 Line Editing and Output Control
The CCP allows certain line-editing functions while typing command lines. The CTRL-key
sequences are obtained by pressing the control and letter keys simultaneously. Further, CCP
command lines are generally up to 255 characters in length; they are not acted upon until the
carriage return key is pressed.
