DBChange Plus Command Formats
* DBChange commands are in the format of one or two keywords plus
parameters. The keywords specify the function. The number of
parameters varies according to the function. Some parameters are
required, while others are optional. If you omit an optional
parameter, the DBCPLUS program uses the default value.
* Commands and keywords can be abbreviated. In the command syntax,
the portion of the command or keyword enclosed in brackets ([ ])
can be omitted. For example, A[DD] FIELD can be abbreviated to A
FIELD. Command and keyword abbreviations are shown in Table 10-1.
* Parameters are positional; they must be entered in the exact order
shown in the command syntax.
* A minimum of one blank space is required between keywords. A
blank space or a comma must be used between parameters. A blank
space or comma can be used interchangeably.
* Some commands use a slash (/), a left parenthesis, or a right
parenthesis as a delimiter between two parameters.
* Some commands use an exclamation point (!) to designate a primary
path.
* Some commands use an @ symbol to designate "all."
* With the exception of passwords, DBChange Plus is not case
sensitive. DBChange Plus automatically upshifts all alphabetic
input. Passwords, however, must be entered by the user exactly as
they appear in the schema.
* The maximum length of a command is 3 lines, each line containing
72 characters, for a total command length of 216 characters.
DBChange Plus does not read any characters exceeding the 72 per
line maximum or the 216 total maximum. If a command does not fit
on one line, use an ampersand (&), preceded by a blank or comma,
as the last character on a line to indicate that the command is
continued on the next line.
* Only one command per command line is allowed. A command can be up
to three lines.
