D1: Number of write words, starting write position
• D1 and D1+1: Number of Write Items
• D1+2 and D1+3: First Destination Word
The 8-digit hexadecimal value in D1+2 and D1+3 specifies the starting write word from the beginning
of the file.
Note • D1+2 and D1+3 are used only when overwriting data, and only 1) For text and CVS data with no carriage returns
(i.e., bits 08 to 11 of C set to 0 hex) or 2) for binary data. Always set D1+2 and D1+3 to 00000000 hex when writing
data with carriage returns (i.e., bits 08 to 11 of C set to between 8 and D hex).
• D1 to D1+3 must be in the same data area.
D2: Filename
• D2 is the starting address of the words containing the absolute path and filename in ASCII. Use
ASCII a to z, A to Z, and 0 to 9.
• The full path name to the directory containing the data file can be up to 65 characters long, including
the starting slash (ASCII 5C). The filename can be up to 8 characters long, but null characters (ASCII
00) are not allowed in the filename because the null character is used to mark the end of the
character string. Do not include the filename extension; the .IOM, .TXT, or .CSV extension is added
automatically. Fixed at .IOM and thus not specified.
• Separate the directory name and file name with ¥ (#5C).
S: First Source Word
S specifies the starting address containing the data that will be written to the file memory.
