FNUM 

The FNUM function returns the MPE XL file number of a file.  This is used
primarily when calling MPE XL file intrinsics.

Syntax 

FNUM(fnum)

Parameters 

fnum             The file number that HP Business BASIC/XL uses to
                 identify the file.  It is a numeric expression that
                 evaluates to a positive short integer.  An optional #
                 can precede fnum.

Examples 

     100 MPE_num = FNUM(1)  !MPE_num is the MPE file number of file 1.
     120 REM                !MPE_num can then be used to call intrinsics
