"In Use"

  The only way to clear this error is to do a Soft Reset.

  To avoid it in the first place, DO NOT interrupt a Cataloguing of  files  in
  RAM  - i.e if you choose to CATALOGUE FILES ( <>CF ) go on to the end of the
  list before ESCaping, otherwise the last file you got will be "in use".


BBC tips which are also useful for the Z88.

    When in Basic you can -

  a)Rename a file.     100 *RENAME filename newfilename

  b)Erase a file.      100 *ERASE filename

  c)Obtain the ASCII code for any keypress -
            10 PRINT GET
            20 GOTO 10         - yes, that's all!

  d)When testing a Basic program using Random numbers it can sometimes be very
    useful  to  be  able  to  repeat  those  numbers in successive runs of the
    program.  This  can  be done by simply inserting the following line at the
    start of any listing   -  Line No. X=RND(-8) (any negative number will do)


Screen display adjustment.

  It is possible on almost all Z88s to turn back the adjusting  wheel  at  the
  left  of  the  keyboard so that the screen is blank.  This should not happen
  for, when powering up with a Hard Reset, the screen can be blank and  it  is
  thought that something is wrong.

    To avoid this frustrating occurrence, before it happens!, take out the keyb
    screws holding the screen.  Carefully  bring  the  keyboard  forwards  and
    upwards so that you can see the variable resistor VR2, just above slot 1.

    Turn  back  the  adjuster (VR1) at the left side and then adjust VR2 until
    the INDEX screen is just visible.  Replace the keyboard and all screws.

  Now  you  should  only  have  a  completely blank screen if there is a fault
  requiring a reset.

"The Home RAM"

  When a Basic or Pipedream file is saved to the Filer, without specifying the
  RAM, e.g with  SAVE "filename" when in  Basic  or  with  <>FS  and  entering
  the  filename  when in Pipedream, it will go to the " current device" , i.e.
  the RAM you would find if you keyed  []F   -  better read that again !!

  If, before saving the file, you go to the RAM in which you want to place the
  file  and  then return to the application with ESC then you will not need to
  type the  :RAM./  before the filename, since it IS  going  to  the  "current
  device".  Similarly, if the current RAM holds the file you are about to load
  then you don't need to type anything but the filename.
                                                                           END
