:Creating Named Directory Files with MKDIR

MKDIҠ i� use� t� creat� Name� Director� Files�� whic� ar� �

MKDIR is invoked with one of three forms:

MKDIR // <-- Print Help
MKDIR <-- Interactive Mode
MKDIR dir:filename.typ <-- Read File First
and Interactive Mode

Th� DIR�� for� i� allowe� i� al� fil� specification� t� �
MKDIR� s� th� use� ca� prefi� � fil� wit� � director� nam� o� th� �
DU�� form�� MKDI� wil� searc� alon� th� command-searc� pat� fo� �
the indicated file.

Onc� th� use� i� i� MKDIR� h� i� prompte� with:

MKDIR Command (? for Help)?

an䠠 h� ma�� issu� th� followin� single-characte� command� �
(striking RETURN is not necessary):

C -- Change Directory (Add, Rename, or Delete Entries)
I -- Initialize Directory
P -- Print Directory
R -- Read in a Directory File

I� al� case� excep� W�� th� scratc� environmen� withi� MKDI� �

the user is prompted with

Unde� th� � comman� (Chang� Directory)� th� use� ca� perfor� �
the following functions:

or lower case) followed by striking the RETURN key.

Example:

Assume the following directory:

A15:ROOT A10:SYS A0:BASE
B0:DEVBASE B1:WORK1 B2:WORK2

If the user wishes to delete WORK1, he types

B1:

If the user wishes to rename WORK2 to WORK12, he types

B2:WORK12

If the user wishes to add WORK3 as B3:, he types

B3:WORK3

I� al� cases�� lower-cas� character� ar� converte� t� upper-�
case.

Getting on with the commands, they are:

C -- Change Directory (Add, Rename, or Delete Entries)
I -- Initialize Directory
P -- Print Directory
R -- Read in a Directory File
S -- Status of MKDIR Environment
W -- Write out a Directory File
X -- Exit
? -- Print Help Message

C has just been discussed and ? is obvious.

:Printing Named Directory Files and Buffers with PWD

PWD (Print Working Directory) is used for two functions:

1. To print the name of the directory you currently
reside in

2. To print the names of all directories you can
access from where you are

PWD is invoked by the following forms:

PWD // <-- Print Help
PWD <-- Print Current Directory
PWD DIR <-- Print Directory Info
