DBCLOSE
The DBCLOSE statement terminates database access, makes a data set
temporarily or permanently inaccessible, or rewinds a data set.
Syntax
DBCLOSE dbname$[,MODE[=]dbclose_mode]
[,DATASET[=]dataset]
[,STATUS[=]status_array(*)]
Parameters
dbname$ A string variable, whose value is a TurboIMAGE database
name. dbname$ must be the variable that was passed to a
successful DBOPEN.
dbclose_mode A numeric expression that evaluates to one of the
following TurboImage database modes:
Mode Effect
1 Terminate access to entire database and
ignore the dataset parameter.
(Default)
2 Terminate access to dataset, but leave
database open.
3 Rewind the data set.
dataset A string expression with a maximum length of 16
characters. Its value is the name of a data set. The
name must be left-justified and if shorter than 16
characters must be terminated by a semicolon or blank.
This parameter can also be an integer or short integer
corresponding to the desired dataset number.
status_array A 10-element short integer array to which TurboIMAGE
returns an error code. If an HP Business BASIC/XL
database statement specifies the STATUS option, an error
does not abort the program. Following execution of the
database statement the program can check status_array
and handle the error. The values returned by TurboIMAGE
to this array are detailed in the description of the
status parameter of the equivalent TurboIMAGE library
procedure.
