Operational Commands

The following is a list of commands that can be entered at the DBINSTAL Cmd: prompt during program operation.

System Commands - Execute a system command from within DBINSTAL. See below for more details.

B[;buf=n][;nomr][;status] - (Letter B) Build the indexes.
;buf=n sets the buffer size where n is the number of MegaBytes, 2 - 512.
;nomr is
;status outputs indexing status information to a file.

E or / - (Letter E or forward slash) Exit to the database prompt. This takes you back to the Database or Environment: prompt. Enter an environment filespec to install or build indexes for another environment file, or enter nothing to exit DBINSTAL. Can also enter QUIT at any prompt to immediately exit DBINSTAL.

H or ? - (Letter H or question mark) Display help information.

I - (Letter I) Install indexes. If an index installation already exists for the connected environment file, DBINSTAL will display a message stating that the "Existing installation will be replaced" along with a listing of the existing indexes. It then begins the MDK Index installation.

INDEX - Synonym for the B command.

L - (Letter L) Display a range of keys to the screen or a file.

M - Enable or disable bitmap merges for an MDK table

MI - Display a map of installed indexes.

P=parentname - Link a child table to its parent by entering P=parentname at the Link column #: prompt.

QUIT - Immediately exit DBINSTAL. Can be passed at any prompt.

Set UTIL {ON|OFF} - Enable or disable diagnostic info display

T - (Letter T) Load a translation table.

V - (Letter V) Display version information and existing installation version information.

X[!] - (Letter X and optionally an exclamation point) X loads an excluded words list.
X! clears an excluded words list.

Z[!] - (Letter Z and optionally an exclamation point) Zap the existing index files.
Z erases the contents of the index files except for a portion of the root index file.
Z! deletes the physical index files from the operating system.

System Commands

System commands can be executed from within DBINSTAL by preceding them with one of the following characters:

! (exclamation point) executes the command as typed

: (colon) upshifts the command before executing

$ (dollar sign) upshifts the command before executing

Syntax:

{! | : | $} command_string

For example, on the UNIX operating system:

Entering !ls at the DBINSTAL Cmd: prompt would list the files in the current directory.

Entering $ls would return a command not found error, because DBINSTAL would upshift the command before passing it to the shell.
