Description
• The ZMOVE instruction is used to transfer data from the area in memory specified in
<transfer source> in a BASIC program to the area specified in <transfer destination> as is.
The transfer is carried out transparently in units of one byte for the amount specified in
<number of transferred bytes>.
Specify the location from which the data transfer should be started, by the offset value in
byte units relative to the starting address of the memory area that the <transfer source>
occupies. Similarly, specify the location from which the transferred data should be stored,
by the offset value in byte units relative to the starting address of the memory area that the
<transfer destination> occupies.
• The ZMOVE instruction allows data transfer between two variables that cannot normally be
assigned by the LET instruction (numeric value character).

• For <transfer destination>, specify the variable, etc. to which the data transferred from
<transfer source> will be assigned.
• Store dummy data in the variable used as <transfer destination>, before executing the ZMOVE
instruction as shown below.
If such dummy data has not been stored, an error occurs when the ZMOVE instruction is executed.
Integer variable
%=0
Floating point variable !=0, #=0
Character variable $=SPACE$(255)
• Always define an array used as <transfer destination> using the DIM instruction, even if the number
of elements used is 10 or less.
Furthermore, in cases where a character array variable name is to be used, store dummy data as
shown below in the specified elements.
$(n) = SPACE$(255)
When the ZMOVE instruction is executed, only the data in the specified elements in the array variable
name become the target range for the transfer.
• A two dimensional array cannot be used in the ZMOVE instruction.
