WORKFILE IS 

The WORKFILE IS statement identifies the file, called a workfile, that
holds the record pointers of the selected records in the database.  This
statement is global in nature and deactivates any previously defined
workfile.  The file designated as the workfile must be open.  The
workfile itself must be a binary file with record size (in words) equal
to twice the number of data sets in the THREAD IS statement.  It must be
defined before the SORT or SEARCH statement is executed.  Since the
workfile is, by definition, a user-defined file, it is subject to the
same rules and restrictions that apply to HP Business BASIC/XL files.  In
addition, open it with both read and write capability.

Syntax 

WORKFILE IS #fnum 

Parameters 

fnum             A numeric expression that evaluates to a positive short
                 integer greater than zero.  The value is the same as
                 that used to open the workfile.

Examples 

     100    ASSIGN #1 TO "filex"   !File #1 is filex
     200    WORKFILE IS #1         !filex is the workfile
