All char fields are case sensitive (i.e. morstatt != Morstatt). => date Date in YYYYMMDD format. Valid values: YYYY = 0000-9999, MM = 01-12, DD = 01-31. => time Time/date combination in YYYYMMDD-HH:MM:SS format, colons and dash required. Valid values: YYYY = 0000-9999, MM = 01-12, DD = 01-31, HH = 00-23, MM = 00-59, SS = 00-59. data Raw data with no format or content restrictions. Data fields are always immediately preceded by a length field. Caution: may contain the delimiter (SOH) character. float Sequence of digits with optional decimal point and sign character (ASCII characters "-", "0" - "9" and "."); the absence of the decimal point within the string will be interpreted as the float representation of an integer value. All float fields must accommodate up to fifteen significant digits. int Sequence of digits without commas or decimals and optional sign character (ASCII characters "-" and "0" - "9" ). The sign character utilizes one byte (i.e. positive int is "99999" while negative int is "-99999"). Examples: 723 in field 21 would be mapped int as \|21=723\|, -723 in field 12 would be mapped int as \|12=-723\|.   | | --- | | ![](https://www.onixs.biz/hs-fs/hubfs/fix-dictionary/img/spacer.gif?height=5&name=spacer.gif) | - Follow OnixS - [Follow us on Twitter ](https://twitter.com/onixsbiz) - [Connect with us on LinkedIn ](https://www.linkedin.com/company/onix-solutions/) We track how people interact with our online web content and resources, and some of that tracking involves storing cookies on your device.
