V_ALIAS()
Return the alias of the current or a specified DBV work area
-------------------------------------------------------------------------------
Syntax
V_ALIAS( [<nDBVArea>] ) -> cDBVAlias
Arguments
<nDBVArea> is any valid DBV work area.
Returns
V_ALIAS() returns the alias of the DBV work area <nDBVArea>. If no
<nDBVArea> is specified, then the alias of the current work area
is returned.
Description
V_ALIAS() is used to return the name of a DBV work area. This name
is either the name of the DBV file or the name specified as the
second parameter in the V_USE() function. If there is no DBV file
open in the <nDBVArea>, V_ALIAS() will return a null string ("").
Any function which accepts a DBV area as a parameter can also
accept an alias in place of the area.
The alias is always returned in capital letters regardless of how
it was passed to V_USE().
Notes
. Do not confuse Clipper's alias names with FlexFile's; they are
mutually exclusive. For example, you can have a DBF file with an
alias of "MYFILE" and simultaneously have a DBV file with the same
alias.
Examples
// Open two DBV files in two new areas.
V_SELECT(1)
V_USE( "file1", "file_one" )// Creates if not existing
V_SELECT(2)
V_USE( "file2" ) // Creates if not existing
? V_ALIAS() // Returns: file2
? V_ALIAS(1) // Returns: FILE_ONE
