DBEXPLAIN 

DBEXPLAIN prints a multi-line message on MPE's standard list device,
usually a terminal, which describes the most recent TurboIMAGE library
procedure call.  Information about the results of the call are explained
on the basis of the information contained in the status_array parameter.
In the event of an error, the message printed is more detailed than the
message returned by the DBERROR statement.  This statement must be placed
immediately after the library procedure call.

Syntax 

DBEXPLAIN STATUS[=]status_array(*)

Parameters 

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.
