I/O Memory Data Formats Section 3-6
TXT Format When hexadecimal I/O memory data (1234, 5678, 9ABC, etc.) is being copied
to an attached file in TXT format, the data is converted to ASCII in one-word
fields or two-word fields. The fields (one-word or two-word) are delimited by
tabs ([HT]: 09) and a return and line feed ([CR][LF]: 0D0A) are inserted after
the specified number of fields.
Example: Tab-delimited words with a return every 10 fields
Note The TXT file format is compatible with the CPU Unit's READ DATA FILE and
WRITE DATA FILE instructions (FREAD and FWRIT) set to tab-delimited
data.
CSV Format When hexadecimal I/O memory data (1234, 5678, 9ABC, etc.) is being copied
to an attached file in CSV format, the data is converted to ASCII in one-word
fields or two-word fields. The fields (one-word or two-word) are delimited by
commas (",": 2C) and a return and line feed ([CR][LF]: 0D0A) are inserted
after the specified number of fields.
Example: Comma-delimited words with a return every 10 fields
Note The CSV file format is compatible with the CPU Unit's READ DATA FILE and
WRITE DATA FILE instructions (FREAD and FWRIT) set to comma-delimited
data.
