Canon X-07 User Manual page 89

As shown in the diagram, when a RAM card is inserted, addresses are reserved
in continuation with the SK RAM area of the X-07.
Previously, we reserved 1024 bytes for the RAM file.
FsET 1024
The location of the reserved RAM file is different when a RAM card is
inserted and when it is not. When a RAM card is not inserted, the area for the
RAM file is reserved from the highest address of the RAM area. When a RAM
card is inserted, it is reserved from the highest address of the RAM card.
To file into a RAM card
To store programs and data into a RAM card, the RAM file must be creakd
with the RAM card inserted inside the X-07.
Here is the procedure for saving a program from the text area into a RAM
card.
1. Insert the RAM card.
FSET 4096
2.
3. Create a program or load a program into the text area.
SAVE "PROG1"
4.
In step 2, we set the RAM file to 4096 bytes. However, it can by any number
as long as it is less than 4096. But, don't make it so small that the set area
cannot accommodate a program. On the other hand, if you set it too large,
you won't be able to read the contents of the RAM card afterwards. To avoid
such problems, please keep the following points in mind.
Points to keep in mind when using a RAM card
The size of the RAM file is set by the amount specified by the FSET
command.
This area is reserved from the highest address of the RAM area. Accordingly,
everything is fine as long as the status of the RAM area is always the same (i.e.
same type of memory card is always used). However, problems can arise if
you use the X-07 sometimes with a memory card and other times without a
memory card.
For example, let's say that you created a RAM file without inserting a RAM
card. Then, you inserted a RAM card which already contains a RAM file.
What you have now is two RAM files. The RAM file in the RAM card and the
old RAM file you created before you inserted the RAM card.
