EXTRAS/RAMDISK
==============

   Puts the currently active catalogue onto the ramdisk
   (which requires enough memory to be available). This function
   should mainly be used for larger catalogues (with more than 100
   entries) or ALWAYS with slower drives (catalogues on CD-ROM, MO-Drives,
   etc.) since nearly all program features (especially browsing,
   sorting, optimising, updating, etc.) will be executed much
   faster. But it has to be mentioned that any changes to the catalogue
   only exist within the RAMDISK copy and that the catalogue has to be
   re-saved via RAMDISK --> CATALOG to keep these changes permanently
   for the catalogue within the actual data directory.


   * CATALOG --> RAMDISK : Copies the active catalogue to the RAMDISK
                           (specific amount of memory required).

   * DELETE:               Deletes the active catalogue from RAMDISK.
                           Any changes would then be lost.


   * RAMDISK --> CATALOG:  Recopies the catalogue from RAMDISK to
                           the data directory where the present
                           catalogue will be overwritten.
                           After that it will be deleted from the
                           Ramdisk.




   Required amount of RAM: For each catalogue entry the following amount
   ----------------------- of memory is required:

                 -->  greyscaled (small/large)   : appr. 6/8 KB
                 -->  coloured    (small/large)   : appr. 12/16 KB


   Note:
   -----
   CATALOG --> RAMDISK will only actually be executed if, after
   transferring the catalogue to Ramdisk, at least approximately 250 KB
   free CHIP and about 150 KB free FAST memory still remains.
