J.E.Lawrie HINTS-22. v.3 "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 Back to HINTS-INDEX
