RENAME SEXP1,SEXP2

 Function
  Rename (or move) a file.

 Syntax
  RENAME old,new

   old  - A string expression with the old path and/or file name.
   new  - A string expression with the new path and/or file name.

 Remarks
  Similar to how the RENAME command works from the DOS prompt, this
  statement will take a file and give it a new name.  Unlike the RENAME
  command, RENAME will not accept wildcards in the old or new parameters.
  Also, it doesn't require that the old path and the new path be the same
  (the drive letters must match, but the paths need not), so it may be used
  to move files from one location to another on a single drive.  So, you
  could use it to move a file from C:\PCB\NODE1 to C:\PCB\NODE2 (renaming
  it at the same time if you wish), but you couldn't use it to move a file
  from C:\PCB\NODE1 to D:\WORK\NODE1.

 Examples
  ' Swap the PCBOARD DAT & NXT files
  RENAME "PCBOARD.DAT","PCBOARD.TMP"
  RENAME "PCBOARD.NXT","PCBOARD.DAT"
  RENAME "PCBOARD.TMP","PCBOARD.NXT"

  ' Move the file to the backup directory
  RENAME "PPE.LOG","LOGBAK\"+I2S(DATE()*86400+TIME(),36)
