Function DbeInfo() Foundation
Sets or returns the settings of a database engine.
DbeInfo() --> aComponentNames or DbeInfo( <nComponent>, <nDefine>, [<xNewSetting>] ) --> xOldSetting
If DbeInfo() is called without parameters, the function returns a one dimensional array of character strings identifying the names of the individual DBE components. If a particular component is not supported the corresponding array element contains NIL.
Otherwise, the return value of DbeInfo() is the value for the setting within a component DBE specified by <nDefine>. If it is a changeable setting and <xNewSetting> was specified, the function returns the old value.
The function DbeInfo() allows reading or changing the settings of the default database engine (DBE). Function DbeSetDefault() is used to define the default or current DBE. The affected settings depend on the current DBE or on the file format managed by the DBE. The DBFDBE allows settings as to whether records are automatically locked during concurrent write access, or whether they must be explicitly locked using RLock() or DbRLock(). When using the DELDBE (COPY TO...DELIMITED), the delimiting characters can be specified for a record as well as for fields and character strings. When using the SDFDBE (COPY TO...SDF) whether a point or a comma-separates the decimal places in numeric values can be specified.
The function DbeInfo() allows settings of a DBE to be read and changes to be made in the configuration of a DBE by specifying <xNewSetting>. When a DBE is configured, the values are valid for each work area in which a file is later opened using this DBE. When a file is opened in a work area, an instance of the DBE is created. This is a called a database object (DBO) and manages the file open in the work area until it is closed. The DBO "inherits" the current configuration of the DBE. If the DBE is reconfigured after the opening of a file in the work area, these changes are not valid for the files already opened. Use the following table to get more information about the configuration of the various DBEs:

To read or change settings for a work area (to configure a database object), the function DbInfo() must be used.
