򐂰 d or dnn - delete one or nn lines
򐂰 i or inn - insert one or nn lines
򐂰 “ or “nn - (double quite marks) repeat the line one or nn times
򐂰 dd followed by dd in a later line - delete the indicated block of lines
򐂰 cc followed by cc in a later line - copy the indicated block. The target is noted with p (prior
to this line) or f (following this line).
򐂰 “” followed by “” in another line - (two double quotes) repeat the indicated block of lines
XEDIT has many more commands and facilities than mentioned here, but these few
commands may be sufficient for initial use.
4.5 z/VM directory
z/VM users and minidisks are defined in the z/VM directory. There are two forms of the
directory: the source file
9
and the active directory. A special command reads the source file
and creates (or updates) the active directory. Changing the source directory has no effect
until the command is executed to create a new active directory.
If you log on as MAINT, you can access the source directory with one of these commands:
browse user direct c (browse it)
x user direct c (edit it))
If you review Figure 4-5 on page 61 you will note that MAINT’s “C” drive is his minidisk 2CC.
z/VM offers the DIRMAINT tool that should be used for large z/VM systems with many
complex directory entries. For very small z/VM systems, such as a sandbox zPDT system, we
can “manually” work with the directory. We suggest you browse the directory on your z/VM
system to obtain a general look at it. The directory for z/VM 6.2 is more complex than in
earlier z/VM releases. A quick look includes the following:
򐂰 The PROFILE stanzas define lines that may be included in user definitions by using an
INCLUDE statement.
򐂰 Skip over sections such as USER $DIRECT$ NOLOG. These help produce a clean disk
map.

There could be multiple source files, but we ignore this detail here.
