• Overwriting
The 33rd byte and after in the existing file “ABC.DAT” is overwritten with the 16 bytes of data in
$u1000 to $u1007.
$u00100 = 'C:\DAT0000\ABC\ABC.DAT' [Target full pathname]
$u00200 = 1 (W)
[1: Overwrite]
$u00201 = 16 (D) [Size]
$u00203 = 32 (D) [Offset]
$u00205 = 0 (W) [0 fixed]
WRITE_FILE $u00100 $u01000 $u00200
• Addition
The 512 bytes of data in $u1000 to $u1255 is added to the existing file “ABC.DAT”.
$u00100 = 'C:\DAT0000\ABC\ABC.DAT' [Target full pathname]
$u00200 = 2 (W)
[2: Add]
$u00201 = 512 (D) [Size]
$u00203 = 0 (W) [0 fixed]
$u00205 = 0 (W) [0 fixed]
WRITE_FILE $u00100 $u01000 $u00200
Supplementary information
• If the name of a new file you intend to create is already used, delete the existing file first and create
a new file.
• If the size specified with [F2 + 1] and [F2 + 2] is zero for a new file, an empty file will be created.
• If the file you specified for overwriting or data addition does not exist, an error will result.
• Wildcard characters (such as “*” and “?”) cannot be used for a full pathname as the target, to which
data is written.
• If an illegal full pathname is specified, this macro command does not work. An error will result.
• In the event of an error during writing to a file, the data having been written remains in the file.
• For the V8 series, the result of macro execution is stored in $s1062.
When the execution of the macro is normally complete, the value at the address is not updated.
Therefore, before macro execution, resetting the value at the address to zero is recommended.
